my 86 grand prix, good times, bad times.

[srercrcr]

In the years I've been on here, all the posts I've read say using any 200 is the weak link in a strong powertrain. I would remember it, cause I have a '78 version of the 200 in a all-stock car, don't need it beefed up.

You can build a TH 200 4R plenty strong for that engine, it just seems that the shop that built it failed to do so. Try to find out what failed as it would be interesting to know. Also, compared to a TH 700, it has a much better ratio spread. That is one of the nice things about it.

yeah i'll find out what happened. seems like something snapped between the torque and the guts of the trans--- the pump is still working but trans does nothing when you put it in gear--- no clunk, no roll nothing.

wrong section for this i think.

and you can make a 2004r strong but i wouldnt expect a local transmission shop to do it though...unless they're known for beefing up these things. they're not the same as a th350 or a 400.

i love warranties though. too bad i lost mine...good reason to upgrade to an OD transmission though! 3 speed autos FTL! you cant run a decent gear without wrecking your gas mileage.

wrong section, but the grand prix forum gets little traffic...

the shop that built the trans is a huge trans shop, that has built many high performance units--- but stuff happens

i love OD trannys. i wouldn't get anything else for a street car IMO

I you don't mind telling us who the builder is, I would like to know.

I'm fairly certain you will need to send yours out to one of the 200 4r gurus if you want it to last and it isn't cheap. Pulling it in and out isn't fun either.

If you want to try to build one for your self these guys have a manual and hard parts. http://www.ckperformance.com/resources/ ... TALOG.html

i'll let you guys know only if they dont come clean on the warranty--- otherwise it's not too fair.

thanks for the info though.



my buddy and i pulled out the defective trans, and threw in my old one for now so i could get the car around. well we went out foe a quick rip and blew the diff out of it!
