Volkswagen AG 01N

Transmission general data

In 1991, the 4-speed automatic transmission (A/T) 01N (097) successfully replaced another popular transmission solution named as 090. It was designed for FWD Audi cars (A4, A6, etc.) equipped with engines from 1.6l to 2.6l. It was also installed on some VW Passats with different longitudinally positioned engines with the capacity up to 1.9 liters.The transmission, manufactured from 1991 to 2004, has three modifications corresponding to their production years: 1991-95; 1996-1998; 1999-04. Thus, these versions have some differences in the design of transmission components.VW have similar modifications of this family: 098/01P – the engine is located transversely in minibuses and MPVs. VW Sharan, VW T2/T4, VW Eurovan, Ford Galaxy; 095/096/01M – the engine is located transversally for VW and SСODA cars.These automatic transmissions differ in housings and differentials.

Technical issues and repair guidelines

The 01N (together with 098/01P and 095/096/01M) - the leader among Audi-VW transmissions in repair frequency. The 01N steadily holds the third place in demand, behind only a younger family U140-240 and the unconditional leader 5HP19(FL).This transmission is very reliable, maintainable, simple, and some problems usually occur only after large mileages.

Often transmission specialists change only the burned-out 3-4 (K3) packs and Forward-Rev together with bearing discs, separate plastic bearings, gaskets, pump and seals. Electric components and the valve body units usually have tha same issues as in the 01M transmission. The torque converter is the main source of faulty operation of the valve body. The sooner the torque converter lock-up lining is replaced, the less is the wear-out of solenoids and the valve body.

The standard order for reassembly of the old 01N transmission includes filter and complete kits: Overhaul kit, Frictions, Pistons.

Ordered Kits:

-Kit of gaskets and seals;

-Kit of friction components, usually ordered with the kit of steel discs;

-Kit of pistons is the same for 01M-N-P, and it is ordered for most major repairs.
