700r4 lockup question

[84_chevy]

my truck wants to stall out every time I shift it into gear. Could I have some of the same issues you guys are discussing here?

Yes, very possible. Disonnect the electrical connector on the drivers side of the trans (4 pin connector) and see what happens. If it stays running, you know it is an electrical issue, if not, it could be a stuck TCC solenoid or converter clutch stuck on. Another option is you could jack the rear wheels off the ground and see if it still does it. (dont step on the brake when you put it in gear, just get the wheels going right away)

Could also be unrelated to trans but worth checking into....

There are 2 wires that CAN come out of the connector at the trans. a blue and a red. Make sure someone didnt accidently wire in the blue wire instead of the red. The blue is for hooking up a switch if you want to manually lock the converter. The red goes through the brake switch and is energized when the brake switch is not acctuated.

I did say that the brake switch was working. After I hooked up the vacuum the system was working correctly except when cruising in third at 35mph it wanted to lock and unlock so a switch on the dash was my solution. Can anyone say for sure whether on not running with it locked Most of time if it hurt the TCC? I can now tell an obvious difference in all gears. I need a limited slip of some sort now!!
