I bought a 200-4R to put into the Wildcat tonight, and I was told it was from a 1987 Olds 442. That would apparently make it a KZF model trans, with a better set of internal bits, but it no longer has the ID tag on it. Is there any way to tell what model of 200-4R it actually is? Here's what I know about it: Sticker on TC: 8653154 CG6F Cast onto Bell Housing: Hydramatic 86?9224 Also Cast onto Bell Housing: 408 G Stamped into Dr Side of tailstock: 3G2325430 (note: 430 at the end of this sequence appear to maybe be bigger, different font. Also note that the second figure "G" is hard to make out) I confirmed that there should have been a "tag" with all of the other info, so it's not simply that I'm looking in the wrong spots. Googling these numbers and a few variations on them came up with nothing, so I'm hoping an expert here can tell me if I've bought a boring old 6 cylinder 200-4R or not. Thanks for any tips! Either way, I'm going to start putting it into the Wildcat this week. I hope it goes smoothly, as the car is scheduled to be back on the road by the end of April, and I don't have every day to get at it!
They all have a code stenciled onto the valve body that identifies them. I've had a website in my favorites column for a couple years that lists all the 200-4R codes by year and model of the car they were in and I just tried to open it to post the link and I get a 'data retrieval failure' messege. I know this isn't much help and I'll keep trying to open it. If I succeed, I'll post it, but you may be able to find the information somewhere else, or even a transmission shop. Of course, you'll have to pull the pan and get that code first.
pull the pan. the valvebodies sometimes had their codes ink stamped onto the valvebody The CK manual also indicates that the performance coded vbs often had a pink or purple paint stripe applied to them other indicators easoly checked are the governor - look for the "light" weights if its a performance calibration and the band apply servo - performance calibrated trans had the bigger ones, The BRF Grand national had one with 4.192 sq.in. apply area - thats about 2.31" diameter
Thanks for the info gents. I will of course be pulling the pan for an inspection and a new filter, so I'll have a look around in there for the stencilling, the governor weights, and the band apply servo diameter.
Oops, double post. I'll add that I delivered the tranny to the car today, so now they're sitting side by side. I hope they're getting to know and like each other! Surgery starts Monday.
Ok, I've got the tranny apart, and good news - one corner of the valve body is distinctly painted purple. On the other hand, the only stencils on the VB are a white one clearly saying "HC2," another white "45," and a yellow outline that looks like a capital "AL," except the L is upside down. The governor appears to have a white (or nearly white) plastic drive gear on it. I didn't take it out, as everything in the tranny looks good, and I want to disturb as little as possible. The intermediate servo is also an unknown because I didn't take that apart either! So, I still don't really know for sure what the tranny is from, but based on all the "86"s I see cast into every part, I'm pretty sure it's indeed from a 1987 modelt year car, and I guess the [ink [aint indicates some kind of performance VB. Time to put it back together with a new filter and see how it works!
I've just found a post on Turbobuick.com that claims the HC2 valve body came in a B-Body. So maybe a Caprice? Doesn't sound too hi performance, so why the purple paint?? Hmmm... Still can't find a definitive list of VB codes...
What's it matter? The only difference is the valve body and since you already have it removed you can swap in an aftermarket one which wount have any wear and tear on it. The only important thing from a ID perspective is what year range is it. The internals changed a bit every few years so certain parts won't interchange. By the way the B-bodies came with a v8 so the trans wasn't a wimp in those cars. Supposedly the strongest of all of the 200-4r's is the one from a '90 9c1. It had all the improvements from throughout the years and then had all the upgrades. Remember that it was designed to bolt to a V8 in a fullsize car and handle the power needed to chase down the badguys.
