Just installed a 2800 stall TC and it makes a noise when locking up (40-50mph and 4th gear). Gets even noiser if going up a hill during lockup.

Anyone else had this condition? Been told it's caused by pulse width modulation.

Any suggestions for a fix?

Thanks

 

What TC is it?

 

Fuddle. Talked to John yesterday and he had some suggestions. Still looking for inputs however.

 

sometimes when i'm at like 3/4 throttle...which is like almost 4k on the tach, the converter will decide to lock up in overdrive @ like 50 mph, which is like 1600 rpm or something...and it will squeal, i assume this is just the lock-up clutch slipping. is this what you're hearing?

yes, i know, i had the opportunity to adjust the lock-up procedure, but turned it down. i will definately look into it next time my car is getting tuned. but for the time being i just rip it to ~45 and let off the gas, so when it locks up the rpms are hardly affected.

 

mine kinda makes noise but it more sounds like slack in the driveterain(sp) at low speeds like 39-40 when im just crusing..
