  • 4T65E Hardened 4th hub and solenoid upgrade

    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 "channel plate" is used, sometimes the term "case cover" is applied to the same part. The term "cover" applies to the large casting on the driver's side that seals the transmission and holds the engine mount bracket. The term "pan" applies to the oil pan on the bottom of the transmission.

    Parts on Hand:
    • Upgraded solenoids
    • ATF: 10 qts
    • Filter
    • Hard parts (4th hub, shift kit, accumulator upgrade, etc.)
    • Cotter pin (ball joint castle nut)
    • Transmission assembly gel or Vaseline
    • Seals: shaft and lathe cut driver's side case seal.


    Special Tools:
    • 33mm/34mm deep socket -- depends on your spindle nut
    • Engine support beam
    • Strong T-40 Torx(R) bit
    • Cold chisel
    • Heavy hammer/mini sledge
    • Small & medium pry bars
    • Large drift pin or scrap cylinder head bolt
    • Soft mallet
    • Scrap wire to suspend brake caliper

      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?

    The following pages contain information on specific transmission models from the 4T60, 4T60E and 4T65 family(4T40/4T45 and 4T80 information may be in the works, stay tuned). For now, it is NOT an all-inclusive list, but any missing information would be appreciated. Miscellania: 4T60E Differentials with an asterisk are "fine pitch" final drives. Sun gears, internal ring gears, and pinion gears are NOT interchangeable with other final drives. 4T65E with "IMS" have the newer type of s...

    So you have significantly modded your engine and now your transmission seems to be the weak link of your build.
