200r4

[seanrolandwood]

So i picked one up this morning and was curious as to peoples opinion as to the best rebuild kits out there and shop manuals out there as this is my first I'm completely unfamiliar with these transmissions and i intend on doing the work myself, any special tools needed, any little "hey they don't tell you this but......." I'm sure theres people here that have used them and said to themselves it would have been so much easier if i had just known or done this and while i appreciate learning from f*#king up as the next guy I've had my fill of frustration for a while just looking for a little help from someone who doesn't mind handing down some knowledge. Ive already considered hitting up a GN forum but those guys are so into the GN i doubt they'd help when they hear its not for a GN. I know everyone has an opinion as far as 200r4 v. 700r4 well i couldn't find a 700r4 in my price range and this kinda feel in my lap and seeing how it pretty much bolts right in without having change much from my th350 its what I'm rolling with.....thanks for any info or links to where i can get what I'm looking for.

Check out www.turbobuick.com
They have a trans section over there. Most of the guys are pretty decent.

I got your PM, But I cant post pics in a PM.....

Let's figure out what exactly you have, There should be a aluminum plate riveted to the passenger-Rear of the trans case. It looks like this....



CR, Is a calibration Code, The most important code on a 200-4R.

F, Stands for 200-4R.

300, Is the Julian date the unit was manufactured.

87, 1987 model

2, Shift ID, (2nd shift)

CRF, Redundant calibration code in case the paint gets worn off or unreadable.

1310, Serial Number.

Some models have a extra digit for Plant identification.


Once you locate the tag, Pull the pan & get the 3 digit code off the valve body.
A CRF 2004R should have a CR followed by a numerical digit (CR9) for example.
IF the VB & tag don't match....The VB has been swapped

[seanrolandwood]

better pic of #'s in case its hard to make out my phone not the best tool for the job but the id plate reads Cu. 297. B
86. CUB. 3903
the numbers on inside read as
254
0450
D8OBO OR D3OBO CANT BE 100% on which

[seanrolandwood]

please ignore after the most basic of checks i know what it is and its definitely Not a 200 4r trans as the pan only had 11 bolts making a 200 series trans but a pile of sh@t th200c trans thank you all for your time and sugestions and sorry for wasting your time i never even thought to look as i got it from a friend of a friend, only redeeming fact is I'm not into it for any money thankfully.....

[clinebarger]

That IS NOT a 200-4R, It's a TH200-C. which is a 3 speed auto with a lock-up converter.

CUB, '86-'87 305 El Camino.

yeah i noticed that i got it yesterday it was raining something else here put it in the garage without even takin the tarp off of it started doin the research on them and long story short lets just say the cart got in front of the horse there pan was off making pics real easy and as i was posting it dawned on me that the pan bolt pattern looked off did a quick check whata you know a th200c.....seeing how i know even less about these whats the general opinion on theses from what i know is a giant waste of time if I'm ill informed please advise as to the best way to proceed keep this in mind i have a 0 mile th350 waiting for this winters engine refresh would it be worth it to throw money at this transmission or just let it go on to the one of these days pile

Use the TH350 if already rebuilt.

Though the TH200 is very weak in stock form, It can be built just as strong as a built 200-4R. But very few circumstances for putting that kind of money in one.
