transmission swap nightmare

[fabianss357]

Well after picking up my 5.3 for the swap last year I started the hunt for a trans.
The truck had a pre 4l60e with the cable kickdown and since I'm going dbw I figured a newer upgrade was in order.
Well I went on the hunt and found a used 01 60e that was supposedly from a tahoe.
Upon getting it I noticed the bellhousing wasn't a v8 bellhousing.
That should have thrown up a red flag, I know but it was Christmas time and I had a ton of other things fighting for brain cell usage at the moment.
So my dumb arse went and bought a v8 bellhousing and bolted it on...
Tranny served its purpose for mock up and sat untouched for a while.... So now that I'm closer to putting them together I figured I would start on the rebuild for the 60e.
So one afternoon while wasting some time before the wife and I go out to dinner I get the bright idea to run the numbers on the tranny. Turns out this 60e is from an 01 s10 with the 2.2!
I swear smoke came out of my ears.
So did I buy a very expensive paperweight or can this be salvaged?
I planned on a rebuild from the getgo, but I remember something about the ls trannies having a different input shaft or something like that.
Can I build the 2.2 tranny up to handle the 5.3?
If so wth do I do about a converter if the input shaft is different and I'm using an ls v8 bellhousing?
Or should I just go out and hunt down a 5.3 tranny and eat the cost of the crap I purchased?
I'm so pissed at myself for not thinking the tranny purchase thru that I can't think straight on the next step to take. I knew something was up when the bellhousing didn't check out... Geez I shoulda stopped right there.

Wellllllllllll your not at a total loss. The case is all the same, the input shaft I believe is the same, ( I would count the splines on the shaft to be certain, and then count the splines for a v8 60e ). Also worst case scenario, you could buy an aftermarket hardened input shaft, buy a complete "hard parts kit" from company like Monster Trans, or purchase a junk 60e core and use the guts ( ie input/output shafts )

Seems like the output shaft is the same. My driveshaft yoke slips right on.
So if the input shaft turns out to be the same, a rebuild kit for a v8 and the matching torque converter should be all I need right?
(I'll probably add some upgrades while its apart)
It has been a long time since I have messed with trannys so thanks for the reply.
any recommendation on some online transmission parts kits?

Yes then you should be ok, Monster Transmission sells complete DIY rebuild kits with everything you need to make a stout transmission. Give them a call 800-708-0087, ask them any questions that you may be unsure of as well, they have an excellent customer service staff. And they can help you get squared away with any thing transmission related as well.
