700r4 4x4 to camaro conversion

i have a 92 camaro z28. i need to replace my 700r4 tranny. can i use a 700r4 out of a 88 suburban 4x4 and just use my tail shaft and extension housing? both have 350 motors. i know the 700r4s were upgraded in the 90s but the 88 700r4 is freshly rebuilt and supposedly beefed up since this vehical was used for hauling heavy loads. i also know this swap will require disassembling the trans to swap tail shafts. is this whole thing possible and are there any other issues to consider?

Re: 700r4 4x4 to camaro conversion

I'm not sure that the output shaft is the same length. The trans is the same and the tailshaft housing will bolt up, but the output shaft may be shorter due the the fact that the 4x4 trans uses an adapter to mate directly with the t-case. I would check this before gettign your hopes up.

Re: 700r4 4x4 to camaro conversion

can you use turbo 350 short tailshaft housing and a long driveline yoke to make it work.i have a newly rebuilt 700r4 from a 4x4 sub.the housing from the t350 bolts right up and i know you can buy extra long input yokes.just wondering?

Re: 700r4 4x4 to camaro conversion

Anything's possible. The 700R4 and the TH350 share a lot of design elements, so it wouldn't surprise me that the tailshaft housing bolts up. If the housing covers the end of the output shaft, and the spline aren't way up inside then I don't see why it wouldn't work. You would need to make sure that you have proper spline engagement as well as seal surface coverage (or it'll leak). With the driveshaft in the car you need to make sure you have enough travel. If the yoke's up against the tailshaft housing with the suspension unloaded you're in trouble because when the suspension cycles it'll ram the yoke into the housing and break it. If it's too far out you risk throwing the shaft or having something wear out prematurely. The best bet is to get everything in the car and them measure for shaft length or check your mocked up shaft and make sure there's enough engagement and travel. If all that checks out then you're good to go. If not you may need to shorten the shaft or have a longer one made. Around here I can get a brand new steel shaft built for about $180, not as slick as a custom aluminum shaft, but it does the trick and its half the price.
