Default 700R4 2 wd - adaptable to 4 wd?

I need a tranny for my plow truck. (88 Chevy K1500) Came across a good deal on a 700R4 from an 85 Chevy truck, but it is out of a two wheel drive. I have not as much as looked at my tranny yet (nor have I seen this other one)...but does the 2 wheel drive 700R4 have a removeable tail piece such I can just bolt up my transfer case?

Thanks

the transmissions are diffrent and will not interchange...the 4wd trans has a shorter output shaft and diffrent tailhousing to bolt the t-case to. only way you can make that a 4wd is by using a divorced t-case.

corrections. the cases are the same but the output is diffrent...idk if anyone makes an adapter to use a 2wd case.

I think you can remove the tail shaft/cone and put the other one on, however you have to replace the longer shaft with the shorter shaft.

the trans case is entirely diffrent at the tailhousing compared to a 2wd.

alright after doing some research i've discovered that the only diffrence between a 2wd and 4wd 700 is the output shaft length. there is an adapter that bolts the t-case to the trans. only way to put a t-case on a 2wd is a extra thick adapter to account for the longer output shaft.

Ok....let me see how confused I am now...

The 2wd version has a longer output shaft - so I bolt in this thick adaptor, viola...t-case bolts up. Is the overall final length then the same? Otherwise, costly drive shaft issues....

And...anyone know where these adaptors can be found (Ok...i will go check advance adaptors....) If they cost an arm and a leg, suddenly this deal on this tranny sounds like it wont be so good!

Thanks again

Mike

mostly, yes, your overall length will be greater, but not by a ton.

You could always take apart the 4wd trans and snag the shaft out of it.

Ok...so maybe that is the way to go then....but then again, I am less and less liking the sounds of this tranny ....I wanna keep it simple! Only good thing is it comes with a good 350 V8 bolted up to it (which my tired old truck could put to use...)

I have been searching for these adaptors - cant find any online yet - Advance Adaptors web site is messing up - cant get anywhere off their main page.

You should probably try that part more often.

You will be further ahead to have someone swap the output shafts to make the 2wd trans a 4wd. With that 2" aluminum spacer ( I have one and will sell you for $50) you will need to shorten the rear shaft, lengthen the front. Relocate the trans cross member, and extend the shift linkage for the t-case.

The 700r4 is not that hard of a trans to rebuild and the parts are cheap. If you have some mechanical ability and a shop manual you may be able to rebuild the original trans yourself. Might want to check with a local trans shop to see what they would charge if you pulled the trans and brought it to them.

I got a guy down here that does the swap for $550. Nice job, got one of his transmissions in the Orange 88 IROC.

I'm not far away and have a 4x4 trans that you could get the needed parts from, free if you pull it outta the truck.
