Transmission general data
The 4-speed 4T65E was designed on the basis of the 4T60 transmission. In 1991, this gearbox was modified for FWD vehicles with engines (2-4 lit.). After testing, this transmission has been supplied to the market since 1993. The 4T60E was modified in 1993 and renamed as 4T65E. This gearbox is a robust product of GM, which properly operates for the first 5-7 years of service. The 440-T4 has been operating since 1983 on Cadillac named as 4T60, and considered to be quite convenient and repairable. Heavy duty (HD) modification is able to work in couple with 440 Nm engines.

Technical issues and repair guidelines
The torque converter (TC) of 4T65E commonly causes a lot of problems during repair procedures. Bearings is a soft spot in this transmission unit. After covering 200 thousand kilometers bearings may get damaged at any moment. The major repair of this gearbox after 150-170 thousand kilometers requires replacement of all bearings.
Issues with the differential bearing may cause the most expensive difficulties (namely, damage of the sun gear differential together with differential planet gears). Then the oil flow with metal pieces may damage the valve body (VB).The main soft spots of the 4T65E frictions are two friction packages, namely, 3rd Clutch with one-sided frictions and 2nd Clutch.
In terms of design, the VB unit of the 4T60E has a lot of differences in comparison with the solution of the 4T60E. This gearbox is also sensitive to contaminated and overheated ATF as well as damaged differential.In electrical components, solenoids have quite a short service lifespan (it is advisable to check the operability of solenoids when the mileage exceeds 150 thousand kilometers).In case of an old car overhaul with mileages strongly beyond 200 thousand kilometers, it is required to replace worn-out bushings which are commonly ordered in a complete kit.
This gearbox is reliable and not complicated. After a major repair it has a substantial resource, if drivers monitor the ATF cleanness and not overload the transmission by maximum torques.Problems mainly occur in the XC90 using the differential in its design. Volvo cars with this gearbox are not intended for driving off the road as well as on muddy roads.
