I don't remember right off hand, but bowtie overdrives does. I got parts from them for my 200 4r conversion in my 72 GMC. Check their site it might be on there. www.bowtieoverdrives.com

Re: Normal trans temp reading

175-200 is optimal, iirc. My TH350 got up around 225 beating on it on a really hot day, behind a moderate 355. I had a really old bent up external cooler on it at the time.

250 -260 is where you need to start to worry about burning up the tranny.
