repoman, First off, if you not a mechanic, go to a local shop that you trust and just talk to them and see if they'll give you some advice. As far as "I know" this transmission's 4th gear is electronically controlled... I may be wrong. If it is it could be just a control module in the tranny. And to answer your second ?: A 2 wheel drive auto or manual tranny have a differ output or "tail shaft" because a 4-wheel drive has a transfer case maited to it, it will have a shorter tail shaft. This is not as simple as replacing the shaft. When a transmission is put together the tail shaft is one of the first parts put in. So basically your friends transmission will have to be tour apart. And if your going to do that, me personally I'd just have mine rebuilt. either way it has to come apart, and putting old parts back in makes no sense to me. So I would tear my 4-wheel drive one apart "or find a transmission store" and have it rebuilt. But also salvage yards will sell tranny's anywhere from $600-2800 a rebuilt will be in the high 1000's usually. Do a little research, but the easiest way will not be the 2-whee; drive option, nor the cheapest. Good luck. I have changed out a few on my own vehicles, so if you have any questions just repost. :)
in 99 and 2000 they have problems with th torc conver ter not letting the tranny shit in to 4th gear
