I have googled the crap out of this, and can't find a thing. The tag on my 2004R reads a big KD, then 313 901KDE0796 Any ideas or routes to follow?
Sounds like you're outta luck http://web.archive.org/web/20070128173316/http://members.aol.com/powerrslid/thm2004r.html Even these guys don't know what it is o No:
Get the partial VIN off of the case on the other side, about 3 inches forward of the speedo drive. Pull out the speedo drive (10 mm socket) and look at the driven gear and peek inside at the drive gear. Post colors and I'll update you. (my source doesn't list any applicable model either; my ATSG service book lists 1990 KDF and KJF and KTF. See if terminal C is empty on 4 pin connector outside; A is red wire, B is blue wire, C empty, D is black wire) on the inside of the transmission. Don't know color of wires on outside connector (DUH), as I don't know what car it is from to look at schematic. POSSIBLY the same...
Also, simply the fact of it being a 1990 just about rules out it being any performance based model; coupled by the generally accepted olds engine prefix (K**). Probably a 307 olds driven fullsize RWD sedan or wagon. But hey, at least it will have SOME of the better STOCK internals, compared to a 82-84 car. key word:STOCK.
Okay...here's what I found. Towards the front on the speedo side, it says: Hydramatic 8639224 On top there's a 40, a much larger 2, and an X and a G Near the speedo...the stamping is hard to read, but I think it's CLR730587 or 61R30587 No noticeable colors inside the speedo hookup. only 3 pins on the lockup wire harness
1990 cadilac sedan deville; olds 307 engine . DEFINITELY not a performance transmission, but it had the top design STOCK internals. Good for a core... You CAN modify even this trans for performance use, but it'll be spendy. Not much more value than as a core for rebuild in stock, or mild modified condition; I'd say safe behind a mild sbb 350. REALLY needs LOTS of work and $$$ for performance use.
They all need help for a performance application. Not many guys using them in transplants or built up regals who haven't beefed them up at least a little bit. The later ones were used in heavy vehicles making decent torque. That means in a smaller car like the A-body with a small block it should hold up for a while. If you intend to do burn outs or run sticky tires than it'll need some upgrades. In a 455 car it'll need a few more upgrades. 455 and sticky tires, expect to go even further with upgrading it.
The Trans shop I got it from claims that it was built up. The owner said that it could handle 500/500 no problem. I plan on just staying with the 430, with the 212 cam, and nothing special for tires. Also, I'll be running a pretty good sized auxillary cooler out front. Burnouts might happen every now and then, but I'll definitely never see any track time with her. This is more of a driver. Cruises, ice cream with the family, stuff like that. if the owner of the trans shop is being straight up with me...I'm thinking it should do the trick.
Now the TRUTH of the matter comes out... You never said anything about it being high performance rebuilt already. Basically they used a good core, and did a hi-po rebuild. You need to find out from the shop what governor it has, valve body it has, what mods have been done to it (type and how many clutches and steels in each pack; upgrades; cup plugs; apply band width and material. Need to know what gears are in the governor and speedo drive. We can't do a thing to help you without the correct information.
