Hey guys, i need to know if this is a tranny, or a stall problem. When im cruising like 60 mph, and the tranny shifts into drive and the converter locks up. after a couple of minutes/miles it will unlock, (even with the cruise set). then it will lock up after a couple of miles. then keep doing this locking and unlocking? is my stall wearing out or something else?? please help.

oh ive got mods in sig, with a fuddle 3600 and big tranny cooler.

 

anyone??

 

You might be having some misfires.. Do you have an SES light? Mine was doing this, and bumped up my misfire tables with EFI Live and it stoppped.
