Re: 200-4R Rebuild

The code you choose will be more about shift scheduling. None are going to work well without mods. A CQ or CZ would be close but an AA will work. A KC code can be made to work very well. OG is common and will work OK with mods.

Just get a core. You can source a valve body seperately if needed.

Do you by chance build transmissions for Red Armstrong's car?

What do you think about this torque converter?

“The heavy duty unit comes with reinforced fins hand welded in primary and turbine with Torrington bearing with carbon kevlar lining. No, anti-ballooning plate.“

I currently have a complete 89 Oldsmobile custom cruiser 2004R transmission but an 85 cutlass supreme became available at the local pick-a-part. Should I grab the valve body from the 85 cutlass?

Grab it all, cores are getting hard to find.

Do these splines look normal?
Isn’t there a way to remove the pump with a pry bar?

Re: 200-4R Rebuild

Those splines look hammered.
Pull the front pump bolts out and look into all the holes.. there may be 2 of the holes that are threaded a larger diameter.
Find a bolt that thread diameter and twist it into the hole and you can use it and a claw hammer or other leverage device to pull the pump.. sometimes.

Upon inspection the drum looks and feels ok. No defects. Should I still take it to the machine shop to get polished?
This other piece is missing two springs. I don’t remember what it’s called.

Re: 200-4R Rebuild

You should check it to make sure it is flat. Looking at that one the wear marks look like it should be OK.

Anybody care to chime in regarding rebuild kits and other parts I should upgrade?
I have a KC5 valve body.
I’ve heard conflicting opinions about a 7 vs 10 vane pump.
I’ve heard the sun gear shells were hardened after 1983 so I don’t think I’ll need to replace mine.
I don’t want to spend the money for a high performance rebuild but I’d like to build something that will last.

Re: 200-4R Rebuild

I run a "stacked plate" style of cooler, not the finned style. Mine is mounted to the passenger side inner fender with a seven inch fan that turns on whenever the passenger side electric fan turns on.
