Percolation? Heat soak? Don't drive during summer??

Good news everyone!!!!

I just took the car out, its 90 degrees outside right now in Las Vegas. Starting the car up the coil wasnt freaking out and the tach is hooked all the way up. I drove for about 30 minutes, not many stops, mainly between 35-70mph (mph is just a guess based off other cars since I didnt hook up my speedo). My car didn't stall once and the temp stayed at 190 degrees the whole time.

I guess I'll drive it a couple more times when its different temperatures outside and see what happens!

Thanks for all of your help in helping me narrow down the problem and getting it fixed!

..... now I just need to figure out my shift points on the transmission... i hate them after rebuilding the transmission, new rebuilt tc and tf2 kit on a 73+ valve body. I know its supposed to be 18mph 1-2 shift and 28 2-3 shift. But the 1-2 shift is garbage and can barely be felt then the 2-3 shift seems like it happens really quickly and is hard (I want them both hard shifts, I drilled the vb to coffee spiller mode...)

AWESOME!

Getting the trans to work right I think will take a proper pressure gauge. I'm not an expert on auto transmissions at all, not in any way, but when I was running my 904 I had a similar thing going on. The 1-2 was soft and sometimes I didn't even notice it shifted, but then it would bark into 3rd.

Might be a good idea to start a new thread in the transmission forum and ask for some guidance on fine tuning. I'm sure your local helper member can probably give some good guidance too!

Also, don't stress the mph on the shift, rpm will translate better to your modified stall and camshaft. Optimum shift points will depend on what your power curve looks like and rear end gear - but I don't think you're so far from stock to complete ignore the OEM recommendations.
