F'in TCC Solenoid!

[S10xGN]

Whenever my truck would get hot, the TCC solenoid would stick and I'd have to downsift manually to first before my engine stalled (idle speed is 1,000). Now that I've finally changed it out, it refuses to lock at all! I can tell you, driving a 9" 3500 stall converter without lockup flat s%ucks! Try going from 2100 @ 70 mph to 2700!

I'm guessing I can test this by jacking up the rear axle (just off the floor), letting the tranny upshift past first, and grounding the two outside terminals (TAN/BLK <-> BLK/WHT) on the ALDL connector. This *should* lock the converter - right? Anything else I can look for (besides brake switch) before pulling the pan again?

Thanks!

Are you absolutely sure you wired the solenoid properly? If you reversed the polarity, you may have popped the diode in the new solenoid. Take a multimeter and measure the resistance across the solenoid terminals at the transmission case connector. You should see around 25.5 ohms.

Well, did I ever tell you getting old $ucks? I finally got around to troubleshooting this thing today and found the brake pedal switch connector hanging in thin air! A few weeks ago, I had it off to install a tap for Razor's alky kit... Hmmm, did I or didn't I? Maybe it was loose and fell off... yeah, that's it - it fell off!
