    Default Replacing my VP auto trans. How to?

    Hey guys.
    In the next couple of weeks I'm looking to replace my slipping auto trans.
    Just wondering if anyone can give me some info on steps and best ways to do this or post links to any relevant info.

    I'll be doing it at home and haven't really looked much into how I go about doing it.
    I'd rather not take it to a workshop as It's not worth the cost and I'd rather learn myself.

    Thanks, Ryan.

    personally i wouldnt even try and do it without a hoist, to hard, take about 4 hours if you havent done one, there pretty easy, take off tail shaft, exhaust, undo cooler lines, take out bell housing bolts take it out. be pretty hard to try and line it up and get it back in on the ground.

    Find a decent set of car ramps so the car is up high enough to work under easily.Also you will need a mate or two to help lift the trans out/in.Autos arent that hard to line up when reinstalling the trans,just make sure that the torque converter is clicked back in the trans properly,it will click back about 2 or 3 times before its fully seated in the trans..Id also suggest you get a workshop manual and follow its steps to remove/reinstall the trans,it makes it a lot easier that way.

    Yeah I have done one in a drive way before. Plenty of swearing. A trolly jack is a must at the very lest, you need something to support the box and have it slide back at the same time.

    Yeah, it's an unpleasant job to do on the ground.

    The auto cooler lines can be tricky. I would not attempt them without a pipe spanner - 1/2" or 5/8"? can't recall which.

    You need to undo the three bolts between the torque converter and flex plate before removing the trans.. The torque converter will stay with the trans.. Apply Loctite or similar when reinstalling them.

    A plug for the extension housing - the front yoke from an old tailshaft is ideal - will avoid a mess when manouevring the trans out.

    Washing/degreasing under the car first - a day or two before, so it's dry - will make it more pleasant to work on.

    The trans. dipstick tube will have to be removed to get the trans. out from under the car.

    I would use 4 stands rather than ramps as it's easier to work on everything with the car level.

    A trolley jack - a real one not a cheap toy - and a block of wood to spread the load across the pan will help a lot in getting the trans. in and out unless you (and your mate?) are built like Mr Universe.

    Flush the auto. cooler and lines through to avoid contamination killing the replacement trans.

    Adjust the kickdown cable when it's all back in: push the locking tab in to release the cable then fully open the throttle by hand to the stop to drag the cable back to it's adjusted position. Be carefull when removing that cable from the throttle body too; it's easy to break the connector.

    Use a screwdriver wedged between the rear tailshaft uni. joints and the floor to stop the tailshaft rotating when undoing the tailshaft bolts but be careful of the dust boots on the uni. joints when doing so.
