when the TC locks up it wont unlock unless i tap the brake once, it seems to be getting worse. any suggestions? this is on the stock torque converter

 

That is how it is programmed. It will unlock if you go over a certain throttle percentage (takes quite a bit, 50-100%), fall below a certain speed (35mph in OD) or use the brakes.

If it didn't unlock, your motor would be killed if you came to a stop, the same as not pushing in the clutch with a manual.

 

so this is normal, like when im driving at 45mph and the TC is locked up, when i give it gas it wont kick down, it will just stay at the locked RPM and i cant speed up, but it will unlock if i go 3/4 throttle and over and kick down so i can speed up.

 

Yup, what you described is normal behavior. It needs quite a bit of throttle to unlock at highway speeds. That is all tuneable though.

 

but it seems like it just started doing it? and when it kicks down it gows down to 2nd and RPMS raise to 4k RPM which i dont think it should, i think it should go down to third smoothly and raise a few hundred RPM to allow me to speed up which is like what all other cars do?. i guess its just me though

did this happen after you changed wheels? and are they a differnt size than stock?

 

well when i got the car i put the rims on 2 weeks after, it does it with the stock rims and aftermarket.I drove it for about 5 months and then it started acting up. i never noticed it before, something definitly has changed

 

and no one has "tuned" your car?

 

nope its bone stock(except for rims and magnaflow), the lady i bought it fom bought it new and hasnt touched anything with it, just regular maintenance.

 

mine just started doing the same thing the other night. its like when im in overdrive and give it gas the rmps go up like it jumped to third but it didnt and if i give it say 75% throttle it will jump to third. one of the guys i that i hang out with checked the computer with a hand held tuner and said it was throwing a stall lock up code.

 

thanks for the info, its weird. im going to get my checked for codes, maybe time for a new converter, oh well

 

I check with one of the shop mechanics (20 year trans vet) and he said it sounds like a electronic or computer problem.

 

when i pulled my trans dip stick the fluid smells burnt does yours?

 

if you smel burnt tranny fluid, check your tranny cooling lines make sure their not blocked and also check you tranny cooler, if thats not the case sorry to say time for a rebuild

 

you need to take it to a good shop. the tranny fluid should never smell burned. the least you will do is flush the transmission (not just a trans service a full 16 quart change with a cleaner additive). good luck

 

I would look at the TPS readings ,

 

will a hand held tuner read those codes? when we hooked it to my friends handheld tuner and it showed a MAF sensor, torque converter lockup, and a o2 sensor code. The MAF sensor code is from my K&N oil from the filter, and the o2 code is from me not having cats. Its had those codes for a while. then just the other night it started acting up and showed the torque converter code. Any one else got any suggestions before I pull the transmission this weekend?

 

my car is in storage for the winter soo i cant work on the tranny until spring

 

lucky me I live in florida great wheather all year long!
