last fall at the dragstrip my transmission started doing a "stacked shift" if thats what you call it. At about 20mph or so it goes right through the gears and goes into lockup. I just replaced the tcc solenoid last week and it still goes into lockup at about 20mph. I unplugged the transmissions four prong plug and it shifts like it is supposed to now. I also checked my tv cable and plunger when I had the pan off none of that seemed to be faulty.

Since it is a new tcc solenoid what do I check now?
Bad/old wiring my problem or a junk tcc solenoid from advance auto the problem?

any ideas and tests that I can run would be appreciated thanks!
