Converter help!
I had a new converter made for me last August. Filled out the engine/car spec sheet and sent it over before building the converter. They set the stall at 6800. Put it in the car, and immediately was faster. Ran the car all last fall with no issues, it stalled right where they said it should. Around 20 runs later, into this spring, i couldnt get it to stall past 6400-6500. The car slowed down 3 tenths. I called, they said send it in.
In the mean time, ihad them build me another one, with new spec sheet. Built a new one that stalled around 7000. Immediately the car went back to running fast, maybe even a little faster. I called about the 1st converter, and they said they "really didnt find anything wrong with it" They freshened it and sent it back
After around 20 runs on the 2nd converter, stall speed is back to 6400-6500, and the car is 3 tenths slower again.
Both times, its a consistent slow. It doesnt continue to slow down. Transmission fluid is clean, no shavings. Line pressure is a constant 160. Running a metric 200.
Short version is, had 2 converters built by a VERY big name in converters, and had 2 failures after 20ish runs.
Anyone ever seen this before? Or have anywhere to start looking to find the root cause?
Thanks
Jason
