  • 4T65E Hardened 4th hub and solenoid upgrade


    REASSEMBLY

    Begin raising subframe to transmission so the subframe engine mount bolts are seated into the engine mount.

    Torque engine mount nuts to 35 ft-lb

    Insert driveshaft into transmission and confirm it clicks into place. Slip other end into hub.

    Raise subframe slowly. When the lower control arm is close enough to insert the ball joint stud into steering knuckle, confirm drive shaft is well aligned in hub and begin lining stud up with knuckle. Continue raising until castle nut can be threaded onto stud.

    Thread castle nut onto stud taking care not to spin stud and split boot. Continue raising frame and tightening stud as practical. Once it will stay in place tighten to 40 ft-lb and secure with a fresh cotter pin. Place the brake pads back in the caliper as they were before, remove caliper from wire loop and reattach to the bracket. Torque bolts to 63 ft-lb.

    Once subframe is fully raised insert both front and back bolts. Tighten to ?? ft-lb (Haynes says 133 ft-lb). Be sure to take up slack on the passenger side bolts and torque to spec.

    Align intermediate shaft with power steering rack stud and slip into place. Insert pinch bolt and tighten to 35 ft-lb. Pull boot back out of firewall and slip down to cover linkage. Seat snap fitting of boot over matching portion on power steering rack.

    Insert tie rod stud into steering knuckle. Use a box wrench to hold stud in place or you will split the protective boot. Tighten bolt to 22 ft-lb and then 120 degrees / 2 nut flats past that.

    Install sway bar and suspension link and tighten nut to 17 ft-lb.

    Reattach exhaust nuts, tighten to 144 in-lb.

    Again, remove transmission pan.
    Pry out old filter seal with a seal puller.

    Use a socket to tap a new seal into place.

    Place filter into seal and use a mallet to gently tap into place until *really* secure.

    If a reusable pan gasket is in good shape put it in place with the pan, otherwise use a new neoprene gasket.

    Install pan and tighten bolts to 10 ft-lb/14 Nm.
    Reconfirm all suspension bolts (passenger side subframe bolts?) and steering gear are tight. Replace anti-lock wiring & splash guard.

    Take up slack in driveshaft spindle nut, use care not to apply force that would upset jackstands.

    Re-install wheels and lower vehicle to ground.

    Tighten spindle nuts: 118 ft-lb or (pre 1998? 151 ft-lb)

    Tighten lug nuts to 100 ft-lb.

    Attach shift cable to transmission.

    Reattach wiring harness connectors.

    Attach bracket to radiator support and torque to 21 ft-lb.

    Attach bolts from engine mount struts to radiator support brackets & torque to 35 ft-lb.

    Reattach wiring and air ducts.

    Fill transmission with 8qt of fluid. Expect to add 2 more due to loss from pump, valve body & channel plate removal.

    Start engine and check for leaks. If all looks good take a test drive. Check fluid before shutting off and add as required. Once transmission cools, retorque pan bolts to 10 ft-lb/ 14 Nm.

      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. You have a few options to upgrade the stock 4T45E transmission which can be rather costly, or you can swap to the stronger 4T65E series transmission which seems to be uncharted territory for many. The purpose of this article is to provide a little more insight on what it will take to swap a 4T65E transmission into your 99+ N-body. ...

    by Tbay99Venture
    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...
