The one wrecker has a listing for a Chevy only pattern 2004R out of a 1986 Caprice. My understanding is no such trans exists but we have all sort of stupid combos up here. I will call them tomorrow to confirm. Was the 700R4 an option that year? I just got a TH200 sent from my local wrecker, not even a lock up. He found his only 2004R in the yard with a pan full of chunks. So the search continues for Dr Olds Mileage Machine. It only needs to live behind a 260 for Pete's sake.

 

I have heard rumors of a Chevy-only 200-4R case but have never seen one. I do know that the early 200-4Rs were BOP-only. By 1986 ALL 200-4R cases were unisex. I suspect that person is thinking of a 700R4.

Here's the BOP-only version.

 

no...its BOP or uni-case..no chevy only cases

 

The only reason I ask is most of our cars were sbc powered up here. Was a the 700R4 an option in the 80's Caprice?

 

It is actually listed as a 86 Chevy Caprice 5L, Chevy pattern 200 with od in "A" condition on their site. The BOP dual pattern is shown as a core. From what I found online, a 700R4 is possible. I could get an adapter for a good transmission. I would buy the better adapter this time. I know where a couple of others might be. I want to get this done before the cold settles in.

 

Called them, both their 2004R's are toast, so no seeing this Unicorn. Sounds like my local guy might have one after all.
