Information about transmission 42RLE / 42LE / A606
Initially this gearbox was named as A606 and then, after an upgrade it’s called 42 LE. Now the gear shift is barely noticeable. The gears could change variably from about 3000 spin rate up to 6000 in a sport mode. After 60000 miles the oil change in the gearbox should take place as well as change of oil filter. After 150.000 miles the overhaul is required. The valve body should be changed. Solenoids are usually replaced in a set and all the oil passages are cleaned. Water packing and driver drum are changed as well. Very occasionally severe problems with frictions and still discs could occur, and you should repair your 42LE / A 606 / 42 RLE AT.
42 RLE and 42LE Problems
The breakdown up until 180.000 miles quite a rare case. It is worth mentioning that this automatic transmission is not designed for a fast, aggressive driving. And completely oil quality critical. That’s why it is advised to change the oil every 25.000 miles. Otherwise, lubrication system gets damaged and solenoids will quickly become dirty and wedged. The lifetime of a solenoid unit rarely comes above 120.000 miles. And one else weak point of this gearbox-torque converter. Torque converter becomes useless after 60.000 miles. It is beyond repair and the replacement is needed.
