Guest Anonymous Posted May 29, 2003 Share Posted May 29, 2003 What are the main differences between a 700R4 and 2004R? Which one would be able to handle abuse? Quote Link to comment Share on other sites More sharing options...
Mike C Posted May 29, 2003 Share Posted May 29, 2003 Both are good transmissions. The TH200 4R is a little smaller than the TH700R4. It has less first gear but more overdrive. The 700 has more first gear, and less overdrive. Both can be built to be strong, but neither is up to 400hp stock IMO. New maybe, but not used. If you get a 700 you want an 87 or newer (late 86) as they are stronger stock. The TH200 is the Buick Grand National Trans but was common in other early 80's GMs. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted May 29, 2003 Share Posted May 29, 2003 Mike, your response needs a little clarification regarding the TH200. It was available in several GM vehicles but the version in the GN was special with a different valve body, servo, shift governor, convertor, etc, making it capable of withstanding lots more HP and more important, low-end torque. You usually do not find these laying around in a junkyard and probably not needed for a mild V-8 swap. Quote Link to comment Share on other sites More sharing options...
