Hi,
this is my first post. Bought a 2001 GC Laredo at 121000 miles, rebuilt the engine. Love driving it, but has had a TCC solenoid code come one for a while. Did a filter and fluid change. The old fluid looked fine, no debris in the pan.
I've read that this shouldn't be a problem driving as it just means the converter isn't locked in. But recently went on a two hour drive ( have done this before with now problems) and had the trans overtemp light come on. Pulled over, fluid was definitely hot. waited a bit, then drove with OD off, no further problems. Coming back, same thing happened within 20 minutes, turned OD off, no further problems.
Previous diagnostics confirmed the TCC solenoid problem as well as a possible pressure sensor problem. changed the pressue sensor, TCC code still came on.
I'm wondering if this means I'm starting to lose the converter. My plan is to change out the solenoid pack first see if that fixes the lock up problem but If the overtemp is suggesting the converter is going, I'd just as soon change out the converter, as I'm planning on putting a cold air intake and power chip, and maybe a mild high performance converter would compliment those power adders. Thinking about adding a TransGo shift kit as well, If I'mgoing to have the valve body out.
Having a hard time finding what the stock converter stall speed should be. a Driveway test (brakes on, throttle up til close to engine stall) indicates about 2000RPM. Max torque of the 4.7 is supposed to be at 3200RPM. Any suggestion what stall speed I should target for a mild performance enhancement but still okay for street driving. don't mind firmer shifts.
Any thoughts on this? Thanks for any feedback.
