I was going through some postings on Trannies and this question came to mind. Will I need an adapter to attach a stock 86 V6 to my 88 Getrag Transmission that had a quad 4 on it? My thinking is yes, and where would I get one?
The 86 V6 and the 88 V6 were the same bolt pattern. All 282 Getrags will fit both. You may need to check Rodney's site for adapters if you have a Quad 4 Getrag.

Get a transmission shop to change the bellhousing half of the Quad-4 Getrag transmisson. You'll need the bellhousing from a V6 Getrag (but then you'd already have a V6 tranny anyway?) (these are circa 1992 Getrag trannys)
To clear things up, I have two cars an 86 SE V6 automatic and the 88 Quad 4, 5 speed. I am doing a total restoration on the 88 and plan on using the V6 engine. So what I understand, is that I can use the bell housing off the automatic tranny and swap it out to the 5 speed tranny. Will I also need to get an ECM with a Manuel transmission chip?
Thanks for all the replies, this is a great site with a lot of information.
Well, it looks like I am going to have to rethink this a little more. Maybe just rebuild my Quad 4 with a few high performance parts. ?? Thanks again to all.
You'll either need to get another Getrag 5-speed transmission that fits the V6 or get a V6 Getrag bellhousing to swap onto your Quad-4 Getrag transmission.

Which Q4 do you actually have? The Q4 makes more power than the 2.8 V6, so if you have a running swap, I'd stick with it, and if you want more power, perhaps see about adding a turbo or something.
I have the original stock 88 4 cylinder 90 hp... Just went to a local salvage yard at noon, looked at a LD9 2.4L Twin cam in a 2001 Grand Am. It was still in the car with all the harness. I have a lot to do before I am ready to install an engine, so I have the time to explore my options.
Thanks to all. It looks like I am in a better position with the Isuzu Tranny. It only has 76000 miles on it. But the V6 has 100000 on it. It's a place to start.
I bolted an 88 Isuzu (from a 4 cylinder) to a 3.4. (Nearly identical block to your 2.8.) It worked fine, but I didn't shock load it. (No clutch drops or speed shifting.)
You will need an 85-87 V6 flywheel, due to the way your 86 V6 is balanced.
Buy an 87-88 V6 clutch, but use the Isuzu release bearing. (I specified 87-88 because they are both 5 speeds. I had an 88 5 speed clutch. I know that at least that one will work. I've heard of at least one person having difficulties using the 4 speed clutch with an Isuzu. YMMV.)
Your 4 cylinder clutch will also work, but it is probably smaller in diameter than the V6 clutch, and will likely wear out more quickly.
