Engine/Transmission (1998.5 - 2002) HELP please! Transmission in lockup all the time

[Hooty222]

Hello all, Have a question, My transmission is "locked up"(converter) When I come to a stop it will kill the engine. The solenoid is not engaged (I removed the connector from the side of the transmission). If I get the truck rolling it will shift, down shift and seem to use the lockup function (Turn on and off) if I am in OD and press the button on the shifter to force third gear it will downshift than loose a little more rpm when it seems to go into lockup third gear... BUT coming to a stop it will stall the engine. Stock converter / rebuilt transmission with 5000 miles, TQ with 20,000 miles? not sure. Fluid looks great, no codes using three key turn method. . Thinking the converter pooped the bed???????

THANKS FOR THE HELP

When that happened to me it was the Torque Converter... Sorry,,, Charlie

Converter is definitely the first thing that comes to mind. I have had them pull th eengine way down but not kill it, however, the degree of failure will dictate that.



The only other thing I can think of is a failure in the forward clutches. Does reverse work at all?

I dont know if this will help at all, but it worked for a '94 Cavalier where the converter would lock up, then not unlock when I came to a stop hot, killing the engine. The only way I could get moving was either to make it spin the tires or wait several minutes. It would eventually unlock, then I could start up and go. I unplugged the conveter, added Lucus and drove it for a couple of weeks w/o the lockup. Then I reconnected the converter, and everything worked ok. May or may not help yours, but did this one.



On my '92, I HAVE to put in a bottle of additive when I service the trans or it will NOT behave right, had the same prob on my old diesel suburban. Usually I had best results with Gunk or Lucas. It's not my intention to start a big discussion about additives, this is just what worked for me.

Yea i had the same exact thing happen and it ended up being the converter

Ordered a PATC triple clutch, Hope that fixes it for good. I will post my find.

AND THE ANSWER IS??
Problem was the torque converter. changed it out to a PATC triple clutch and back to normal. In the past I had troubles with 2 TCI value single clutch billet. So hate to bag on tci but one wasn't built correctly (missing a bushing, wouldn't lock up) than second one tore up my front pump thus eating up my transmission. They may have there act together but... . Go PATC and no worries
