Re: Transmission swap- TH350 to 700R4
Hello all! So, tonight I opened the transmission again. There were some afterthought upgrades and tuning adjustments I wanted to make. I changed the metal ball bearings for torlon, removed the stock accumulators in favor for sonnax pinless and installed an internal transmission temp gauge. When I originally put it together, I though I would want a firmer shift but it proved to be too harsh for me. So I went back to the stock accumulator springs, top and bottom. Another thing I did was install the shim in the boost valve that came with the kit. Originally I installed the spring and placed it between the spring and pressure relief valve as in the instruction pictures. This gave me too high of peak pressures. This time I put the shim between the Boost valve and the spring. So far it looks like it is right in range with where it should be. It seems to only affect the high pressures and not the low. I need to do more warm tests though and I'll post the results.
