Stall and lockup questions

[WARLOCK]

I have a Circle D 2500 Stall converter. I was told today that if I didnt have a shift kit my tranny would not hold enough pressure to keep the converter locked up. It dont think their right but I thought I would check.

Also would the tranny wiring be different from a 99 camaro to my 2000 silvy? Or the speed sensor wheel on the shaft?

Just trying to figure out the no lock up problem.

That is not true, a shiftkit is not required when a higher stall converter is installed.

Turn around and slowly walk away from this guy lol jk.

See if you can lock up the converter with a scanner.

Also, everytime the clutches slip and you rebuild the trans, be sure to have the converter flushed and all the lines.

The guy that said this is not the gy building my trans...lol Thanks for the info Allen..

Anyone else have info on the wiring?

A no lock up condition is either an electrical or mechanical issue. You can put a scanner on it to see if it is getting commanded to eliminate a tuning or computer issue. From there I would check the transmission for a mechanical issue, bad solenoid, stuck or damaged valve. It could be a converter issue, i.e. cut O-Ring or bad bonding of the lock up clutch. Not to sound like Circle D never has issues, but it is quite rare. The problem is typically a tuning/computer issue. The last thing I suggest to test is the actual wiring on the truck, I have seen a broken wire cause hours and hours of havoc.

Check brake lights and brake light switch too.

Lockup worked fine one revious trans. So its either the tranny or the converter. but im betting on the trans wiring.

I say solenoid isn't working, from wiring issue or faulty part.

Thats what im thinkin too allen. He is supposed to tear into it tommorow. Hopefully the reason I had a 2-3 upshift lag/flare will be obvious.

Keep us updated. If you can't find anything and need me to check out the converter let me know. Good luck, hope it is easy and obvious.
