    Unbolt exhaust flange from manifold (2 nuts.)

    Remove splash guard from wheel opening.

    Disconnect anti-lock sensor & place wire near radiator and out of your work area.

    Unbolt driver's side tie rod from steering knuckle. Bashing the knuckle with a sledge hammer is one way to free the stud. BEWARE not to twist the stud or you may split the rubber boot.

    Loosen spindle nut to the end of the drive shaft but leave in place to protect threads. Use either a large drift pin or a scrap cylinder head bolt and sledge hammer to pound the shaft inwards & break it free of the hub.

    Unbolt the caliper pins but leave the caliper mount in place on the steering knuckle. Carefully remove the caliper and use a loop of scrap wire to hang it off the suspension spring through a bolt hole. Set the brake pads aside. Remove cotter pin and castle nut from lower ball joint. Break ball stud joint free of steering knuckle similar to the tie-rod stud removal.

    Now remove transmission pan and drain transmission fluid. Temporarily put the pan back in place with a few bolts.

    Place a pry bar as deeply as possible against the inner CV joint's shaft and pry against the transmission housing to force the CV shaft out of the transmission. It should click out of its seat with moderate force. (If your pry bar is too far from the shaft centerline the shaft will not release from the transmission.)

    Swing the front strut & steering knuckle assembly outwards as required to remove the drive shaft from the wheel hub. Support the shaft ends while removing it. Set aside in a clean spot.

    You MUST disconnect the steering shaft from the steering rack when lowering the subframe.
    Release the lower part of the boot from the power steering rack. It is a snap fit.

    Compress and guide the upper portion of this boot so that it slides within the larger boot that protrudes through the firewall.
    The boot is too thick to "accordion" fold it. You MUST slip it through the firewall and into the passenger compartment.

    Silicone spray lube may help.

    Bracket edges and self-drilling screws are sharp. It is best to get an assistant to do this while you go and fetch beer.
    With the boot out of the way, remove the intermediate steering shaft pinch bolt and slide the shaft assembly free of the power steering rack's shaft.

      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...
