Technical issues and repair guidelines
The 6T70 unit is considered to be more problematic in comparison with Ford modification. 6T70 had many problems related to electrics and transmission components. In 2012 several significant updates were introduced with addition of wavelike rings in packs and performance optimization of solenoids plate and the valve body.
The 6F50 / 6F55 (GM 6T70 / 6T75) transmissions found application on rare American vehicles. For rare overhauls specialists usually order the filter with the pan gasket, which should be replaced with ATF after 50-80 thousand kilometers.It should be taken into account that for this class of automatic transmissions it is crucial to monitor the ATF state (DEXRON-VI - GM or Mercon 5 - Ford) and its temperature. The quantity of fluid required for full change is approx. equal to 9.5 liters. It is advisable to repair the torque converter and clean the valve body when having problems with shifting and operation of the valve body with solenoids.
A quick failure of the torque converter caused by contaminated fluid may be considered as a soft spot of this transmission. This problem leads to oil starvation or increased pressure and cranking of bushings. The valve body is repaired by replacement of worn valves with enlarged valves from Sonnax. Problems of this transmission often start with the wear-out of rings and bushings. Contaminated fluid from the torque converter speeds up the wear-out of these seals and damages solenoids.This transmission rarely gets in repair services as well as cars with this good automatic transmission produced by Ford.
