I picked up two 200-4r transmissions today. One was left out in the rain for a long time and the other I pulled from a 1990 oldsmobile station wagon. I'm thinking a 200-4r would be perfect for my 70 cutlass since it has 3.55 gears which are very annoying on the highway. The one out of the station wagon has stickers on it that say its a gm goodwrench rebuild. I figured I could build one good one from these two cores.

I understand that in stock form, these transmission are very weak. I've taken a look at the cpt transmissions website and they seem to be able to provide everything I will need to build a 200-4r strong enough to handle my 350. I picked up a haynes techbook on how to rebuild gm transmissions and it seems to be very descriptive and has step by step instructions for disassembly and reassembly.

I have never taken apart an automatic transmission before and I was hoping I could get some pointers. I understand from reading through the haynes techbook that a few specialty tools are required, in particular a J-28542-A reverse clutch housing remover/installer. Are these tools still available? Wheres the best place to look for them?

Any other suggestions are most welcome. Thanks for the help!!

 

admittedly i know little about the 200-4r but heres a link anyway, looks to be good http://www.turbobuick.com/forums/tra...ing-2004r.html . should get you started.

 

Besides CPT, the other well-known specialist for the 200-4R is CK Performance.

I have their 200-4R tech manual and it is well worth the price. It has a step-by-step teardown and rebuild and shows you both the required mods and how to do without most of the special tools.

I have been collecting the Kent Moore tools on ebay. The factory Chassis Service Manual has a list of all the KM tool numbers and I just set up a search function in ebay to automatically look for them for me.

 

Thats a great link, lots of good information. I think I'll have to read through it a few times.

It does sound like that CK tech manual is a good investment. I'll have to start checking out ebay for those tools! Thanks!!

 

Seeing as how it came out of a 1990 Olds it may already have some of the updated parts...and hopefully the hard parts are in good shape.

Just take your time...take pictures of your disassembly if you like...and dont lose any check *****!....Good luck...its always fun and rewarding to do the job yourself.

 

I would definitely recommend Chris's transmissions.

I bought a Stage II 700R4 from him in 2003 and it lived up to it's name
of quality performance for the few years I had it in my car. Chris has a
great sense of continuing support for his customers as well. I highly
recommend his products.

only reason I still don't have it, is because I put a 2004 GTO LS1/4L60E
in my 78 Camaro in it's place.
