Rebuilding an AW4

What is involved? Can it be done by a garage mechanic? I see cheap transmissions listed where one gear slips. The cheapskate in me wants to buy and rebuild. I've seen rebuild kits for the transfer case, do they make them for the tranny?

They make rebuild kits for pretty much every trans. And actually it would probably be cheaper to find a known-good working trans and install it. I dont know about you, but my time is worth a decent amount of money.

As for the "slipping" it could be caused by something else. As the AW4 is elec. controlled there are a few factors that can affect how it shifts.. such as tps, TCU, wiring, etc.

It depends on the type of garage mechanic. Here is my rebuild http://www.naxja.org/forum/showthread.php?t=962764 It takes some time but when working on my own stuff I usually work for free.

Transmission rebuilds are pretty tricky IMHO if you have no prior tranny experience. Salvage yard transmissions should be pretty plentiful and are a good bang for the buck as well as allowing you to plug and play.

What are the symptoms? You need to rule out the usual electrical issues before you assume the tranny is mechanically bad.
