Not to say my new acquisition (95 -60HD from a Riviera) won't work for my 93. I know about the wiring differences, and that doesn't bother me.

What DOES bother me is the side pan. Bonnevilles (and all H-bodies for that matter) have a stamped-steel pan. G-bodies that got the -60E-HD got cast aluminum "structural" sidepans...something I did not know when I picked up this tranny. I borrowed Dons ATSG manual and from the looks of it, even the output on the sidepan is different and swapping pans may very well be out of the question.

Flashback...Don said something about a shaft having 2 different part numbers but could not for the life of him figure out why...hmm......

I need to get some measurements later...if I can swing with this structural pan, life should be good, provided the axle I have now will work with it. Any thoughts on this?

Dang...a week goes by and not ONE response????

I got more interesting pictures I want to show you guys. This new trans I got is completely unusable as it sits. The front mount bosses are completely destroyed (I didn't see these before as the original mount was still on it. Once I took the mount off, the bosses just come apart) and looks like it was repaired before by using some cheap epoxy. So right now it isn't known if this is the original trans that came with that car (Though the tag says it'* correct for the year and car). It'* a pitty too...this case looks pretty damn tough otherwise.

This didn't bother me so much, but annoying nonetheless.


Here is the rear of the two projects I have. On top is just a case i bought off of ebay some time ago for pretty cheap. On the bottom WAS going to be the donor trans. Now take a look at the differences. The biggest one I noticed was the casting is completely different. Take a look at the structural webbing on the bottom case. This looks like it could be a very stout case for a performance buildup, but this case for me won't work since the mount bosses are shot.


Here are those bosses I am talking about


Finally, here is a look at that structural pan I was talking about. Look at how beefy this pan is!

I'd have posted in here, Brad, but I don't have any info that would help you. Sorry, buddy!

Looks like you have some work on your hands

That I do. The whole point of me getting this tranny was to AVOID a rebuild. But now...I guess I am just gonna have to get my hands a bit dirty and learn how a tranny goes together.

Good thing a garage is on the horizon....

IMO get a used unit from the yard or rebuilt.

Eh, I'm done getting used units now. The 95 HD trans is a yard tranny, and if it weren't for the mounting bosses I would be throwing it in. So all told I have two complete trannies and a case that is near ready to use. Since I am going to be taking apart the good transmission now, it probably won't hurt to go ahead and get the rebuilt kit for it, and possibly the shift kit.

Like the engine, this trans is going to be another Frankenbuild (I say this because now I can make internal changes to the wiring and add the temp switch for traction control), as well as a learning experience. The original plan was to just shove in the 95 trans and rebuild the 93 as a spare, but that'* all fubar'd now. I may very well offer that up to Curt to use as a core tranny in case his takes a dump.

And I'd take you up on it too... Sorry I haven't chimed in before, but I don't know much about the variations of the transmission you were trying to use. Sucks about the mounting tabs. Have you considered having them welded back on? (you'll need somebody good with a TIG welder to do it.)

Welding them would be an option, but I would have to a)grind the "new" case down to the surface and b) carefully cut the bosses off the empty case, weld, and rethread. And that is alot of work when you consider the weight of a fully loaded trans sans the torque converter.

Since the case would be considered trash if it can't be done, I may very well go ahead and knock out the remaining boss material and smooth it out as much as possible, though I am probably going to kill my dremel if I do that. Once smoothed out, and if it is entirely doable to do, I will go ahead and cut the bosses out of the empty case.

Curt, you know anyone good with aluminum welding? Cuz I sure don't
