RE: Transmission Shifts Late at High RPM
when I read my codes, I leave the key in the on position each time untill the lights turn on for three times,on the third leave it on and it might bring up the code. If not, run to the nearest kragen and have them give you a free reading.My truck is doing the same exact thing yours is, I replaced the tps and it helped a little bit, the old tps was rattling! I just have tobaby the throttle to get it to shift properly.Mine is throwing a 1740 code but currently i don't have the dough to throw at it. The 1740 calls for replacing the tcc solenoid, and the overdrive soleoid ( or so all the tranny shops tell me). They're each about 100 bucks from a dealer, cant get'em at napa. Let us know what she says.
