    HUB REPLACEMENT

    DO NOT remove the output shaft. Simply pull the 4th hub out of the transmission.

    Compare the two hubs, ensure there is no internal bushing that must be transferred, etc.

    Insert the new hub, twist and wobble as required to engage the splines and fully seat the hub within the driven gear assembly.

    Take a moment to inspect the oil pump shaft seal, and splines to detect any abnormal wear. If you beat this tranny daily your splines may be showing it, though you'll likely need a lot of other work done if that's the case. (Turbine shaft and sun gear have been reported as wearing out in high load/abuse service.)

      I own an 85 6000 STE with the 'W' engine and TH 125 C. I did not see any specific date for the 'W' engine or the TH 125 C. Will I find any information somewhere else?

    INTRO This is a guide on how to service your transverse automatic transmission without a lift. All work is done with the vehicle on jack stands. Once the cover is removed the valve body is left attached to the channel plate. This assembly can then be moved to a workbench for easier servicing if valve body work is in your plans. In any case the transmission drive chain, pump, 4th gear assembly and many other parts can be repaired or upgraded at this time. In the description below the term "c...
