Technical issues and repair guidelines
With regard to mechnical components typical problems usually occur in the bushing and the pump seal, which are the first to be affected by the torque converter (TC) lock-up wear-out and overheating. The oil leaks via the seal of pump/TC is the the first signal for diagnostics, cleaning of the valve body, and the TC repair. Further operation with such leakages may result in the necessity for the pump bushing replacement, and in some cases replacement of the pump itself.
In the electric part, the first level repair consists of the valve body cleaning and replacement of solenoids. As in many of Aisin automatic transmissions, the torque converter lock-up solenoid SLU is the first to wear out, because this solenoid operates with all contaminated and overheated oil from the worn-out torque converter. Another problematic area is the main pressure solenoid LPC (SLT), which transmits all ATF to other solenoids.
Specialists recommend to monitor closely the ATF condition in the TL-80SN transmission. In case of rapid ATF contamination after the prior partial change, it is recommended to visit the repair shop for the torque converter repair, without waiting for the friction plate wearout, that may be especially harmful for the AA80E solenoids and the valve body. It is also advisable to replace the filter in due time, and check the pan.
The design of transmission components for all RWD Aisin transmissions is considered to be "invincible", having a large structural reserve. This transmission usually operates without serious problems throughout the car lifespan. However to avoid unnecessary repair costs, car owners have to monitor the ATF state, timely visit specialists for the torque converter repair, cleaning of solenoids and the valve body.

Technical issues and repair guidelines
One of the main peculiarities of this transmission in comparison with common automatic gearboxes lies in the electronic control. This gearbox uses 5 solenoids together with the transmission control module and its sensors to control shift timing, shift feel, and give on board diagnostics.
Repair specialists say that the valve body is the most problematic component in TAAT. Delays, slippages, kicks or lack of Reverse during gear-shifting are likely to be caused by valve body issues. However, there are several other sources of a Reverse problem:
1. Delay or no Reverse may be caused by the loose-fitting main shaft nut
2. Malfunctioning car speed sensor may also lead to no-Reverse condition.
3. Wrong adjustment of the pattern select switch

The CVT Honda Multimatic SWRA / SWSA had been installed
on right hand drive cars Honda Fit of the first generation (produced from 2001 till
2007) for the domestic market of Japan. It should be pointed out that Honda Fit
cars for the American market were equipped not with CVTs, but with common
automatic transmissions. Therefore, transmissions for Japanese and American
models of Honda Fit are not interchangeable.SWRA is a continuously variable transmission
produced by Honda. This transmission is used in some Honda cars (Civic, Jazz,
Logo).

CVTs SWRA / SWSA differ from each other not by engines
(with which they operated), but by the purpose of CVT model (for FWD or AWD). In
other words, Honda Fit cars with L13A and L15A engines were equipped with the
same transmission SWRA / SWSA, but there was an important difference:
- SWRA – 2WD
- SWSA – 4WD
As the right hand drive Honda Fit of the first generation
(produced from 2001 till 2007 ) served as a basis for other cars («Honda Airwave»,
«Honda Mobilio», «Honda Mobilio Spike»), then CVTs for these cars were slightly
upgraded (the main difference lied in the housing mounting). These CVTs
received new model names:
·
Honda
Airwave (from 2005 to 2007) 2WD – SLSA
·
Honda
Airwave (from 2005 to 2007) 4WD — SLTA

Fit Aria / Honda City (from 2002 to 2009) 2WD — SERA
In fact all
these car models were equipped with the same CVT. Transmissions differed only in
the drive mechanism (FWD or AWD) and in holders for the CVT case. All other components of these CVTs are absolutely identical.
Therefore, these CVTs may become
interchangeable with the help of several minor modifications. Modifications usually
consist in replacement of holders and some sensors.
According to
Honda’s manual, SWRA / SWSA transmissions require ATF change вариатора (CVT) every 45 thousand kilometers.
When the car operates in harsh conditions ATF should be changed after 22,5
thousand kilometers.
Harsh conditions usually include:
1.Frequent and
short drives - no more than 8 km in the summer time or 16 km in the cold season
(at negative air temperatures).
2. Operations
under conditions of high temperatures (above +32 °C).
3. Long engine
operation at idle speed, driving with frequent stops in traffic jams. Towing of
the trailer or running on mountainous terrain.
4.Driving on
dirty, dusty roads or on the roads which are subjected to treatment with anti-icing
compound.
Honda
Fit cars of the first generation equipped with CVTs SWRA / SWSA often face
problems with the CVT mount, which tears after the car mileage reaches 50-60 thousand
kilometers. Symptoms of this problem include the following: increased vibration,
kicks at starting from rest/braking. Visual inspection helps to detect this
problem. The mount is oil-filled, therefore transmission specialists recommend
using original spare parts.

Technical issues and repair guidelines
This transmission is quite reliable as all rear-driven Nissan vehicles. In terms of design, this transmission is similar to RE4R01B\A and R4A-EL produced by Mazda. Repair parts for this gearbox are ordered in very rare cases. Therefore, in most cases owners of cars equipped with this transmission prefer to replace it with a new or used unit, rather then to spare time and money on its repair.
Typical problems of this transmission are similar to problems of the RE4R01A\B transmission. In most cases, repair specialists order the repair kit of gaskets and seals when they have to deal with this transmission. Sometimes, it is required to replace bushings on cars operating under severe conditions. In rare cases, it is necessary to change one of one-way clutches or set of solenoids, which get cleaned more often than replaced. Not complicated repair procedures for this reliable transmission can add several years to its service life.

Technical issues and repair guidelines
During each overhaul of this transmission, repair specialists replace the kit of gaskets and seals, which should be changed after a long-time operation to prevent the damage of the rubber elements. But the main repair procedure consists of replacement of rings, because their wearout may have a negative impact on the oil pressure in clutch packages. In most cases, repair procedures lie in cleaning and reassembly of the valve body, replacement of gaskets, spare parts, springs (of shock absorber), and the torque converter repair. Every second repair includes replacement of the solenoids block The issue with worn-out solenoids may lead to fluid shortages in clutch packages and result in slipping of friction clutches, oil burning and later burning of all frictions.
Hard parts of this transmission are very reliable. This gearbox may be considered invincible except for oil leakages from the pump seal (occur after 150 thousand kilometers), which usually says about the wear-out of torque converter spare parts and the pump bushing. It is recommended to change the fluid not according to its period of operation, but according to its transparency.
When this transmission unit in old cars is exposed to "oil starvation", then it may lead the following malfunctions ( in the following order):
- Reverse drum with the piston, wear-out of the surface by the brake band.
- High clutch drum. The shaft cranks, different types of wear-out of the shaft surface and drum. Reverse friction elements are prone to burning
If the fluid state in monitored and solenoids are timely replaced, then this transmission unit will operate properly for a long period of time.

Technical issues and repair guidelines
This transmission is quite reliable, but when it comes to the repair of this transmission is can be quite expensive. Thus, many car owners prefer to replace this gearbox by the used one. The problem of “old” RL4F02A transmissions as in all Nissan gearboxes lies in the electronic control elements. The torque converter lock-up solenoid operates quite intensively and gets out of service very early. It was modified several times.The rest of solenoids should also be changed before they stop operating properly, because it leads to the oil starvation, cranking of bushings, deterioration of drums, planetary gears and pump.
But usually issues are related to general ageing of rubber gaskets and wear-out of friction components, which contaminate valves of the valve body and solenoids, prevent springs from moving valve cores. All this results in such common issues as jolts and stoppages. The wear-out of friction elements initially affects the torque converter lock-up mechanism, then worn-out clutches start slipping at some gears and the car ceases moving uphill. Generally, this transmission is quite reliable and has a high operational reserve. After the reassembly and cleaning, this gearbox can operate on the snow and in off-road conditions for a long period of time.

Repair procedures for this transmission usually involve timely fluid change and sometimes filter replacement. Sometimes it comes to replacement of the belt which fits to some related CVTs from Honda and Mitsubishi. In rare cases, burnt Forward and Reverse frictions get replaced. Frictions get burnt because of worn-out rings and gaskets (Repair kit of gaskets and seals). Burnt fluid damages rubber seals, therefore experts recommend to replace all rings of this CVT RE0F21A in the course of overhaul. The major part of spare parts for repair of this CVT is bought on the market of used spare parts, and repair of this CVT is less frequent than replacement for "used" CVTs.

Commonly, planned overhaul of these transmissions consists in cleaning of the valve body, repair of the torque converter and ATF change. These measures are assumed to be enough for another 2-3 years of proper operation, if gaskets are intact and the oil pressure in packages conforms to requirements.The reassembly of this transmission usually includes not only the repair kit of gaskets and seals, but also the kit of frictions and the kit of steel discs. A rather long-lived clutch of the torque converter lock-up may be exposed to wearout. In some cases, it may operate until 200 thousand kilometers. The untimely replacement of the friction component results in beatings, damage of the pump seal, and later breakdown of the pump bushing.
Typical problems of R4A51 (V4A51)
Filters are clogged with wear-out products and there are two modifications of filters for transmissions applied in RWD cars. The planetary gear (O.D.) rapidly gets out of order under the condition of extreme and frequent loads close to the torque limit. In the process of reassembly, the valve body is washed and may operate properly till the end of the car lifespan. During the first overhaul, specialists replace some solenoids that operate very intensively, namely EPC solenoid and the solenoid of the clutch lock of the V5A51 torque converter operating in the dirtiest and hottest fluid. Input shaft sensors get out of order because of old age, oil contamination by steel shavings, and overheating It is recommended to replace all frictions and the brake band in case of a long-term operation with burnt fluid.

The 3-speed automatic transmission Renault MB1 was
released in the early 1980-s. This transmission was used for many Renault
vehicles, such as Renault 5, 9, 11, 19, Clio and Twingo.
This transmission has 3 forward gears and 1 reverse
gear which are combined in the uniform unit with the drive gear and
electronically-controlled differential. The oil pump is activated by the engine
shaft via the torque converter and transmits the oil under pressure to the
gearbox, where it is used as a lubricant and for controlling actuators.

Technical issues and repair guidelines
The most widespread malfunctions of MB1:
• Gear fails to switch on. Any malfunction of solenoid-controlled valves of the hydraulic distributor switches the automatic transmission into emergency mode.
• Oil leakages. In many cases car owners are bothered by ATF leakages. Usually the oil leaks at the junction of the motor and the automatic transmission.
• Critical breakdowns. Low oil level and the pressure loss caused by the valve breakdown lead to burn-out of friction plates.
• Shifting failure. A poor valve body breaks before reaching 100 thousand kilometers. This problem has the following symptoms: jerks, kicks and failure of some gears.
According to transmission repair specialists the resource of this transmission is equal to 100 - 150 thousand kilometers, but it is very unlikely that this transmission will cover such distance without any repairs.

Technical issues and repair guidelines
Like in all RWD automatic transmissions of Jatco, the design of RE7R01A elements implies a very long resource for this gearbox under the condition of preventing operation with contaminated fluid, which leads to the chain reaction: contaminated oil results in worn-out teflon rings, clogged valve body, worn-out solenoids leading to oil starvation of frictions.
It is common to replace torque converter spare parts in the course of overhaul of this transmission. Traditionally, the JR710 reassembly includes the repair kit of gaskets and seals. All rings, gaskets, and seals get replaced. The brake pack В3 (2-3-4-6) is the first to sense reduced oil pressure. Frictions with steel discs get burnt. The pack of С1 (Input) frictions is the second to get burnt. In this case, it is required to replace the whole set of frictions.
