Hi new to site. Have found loads of good info but still can't pinpoint my problem. Please help. My 98' Intrigue with 3800 SII has 87k on newer motor. Original complaint was an erratic speedometer, and hard shifts during city driving once warm. On road trip using cruise control, rpms raced up to 4500-5500 before I knew it, threw a rod and locked up(newer motor). After replacing motor, I got the left SES light on and the trans eventually went out, and would no longer shift. Replaced the trans and now have the left SES, Antilock, and TracOff lights on. The car will drive fine and shift fine until it heats up, then shifting happens at a higher RPM range, and up shifts, and down shifts erratically, or better yet, at will! and will stay in 1st or 2nd gear. I had to drive 4 miles home at 25mph! i just went out to start it up since its been a few days , and the idle is staying at 1500rpm's which is about 500-700rpm higher for my car. From what I undersand the following could be the culprit of my problem('s): TPS, VSS, EBTCM, Shift Solenoid, CPS. I'm just getting fed up with it and tired of putting cash into it at this point. If anyone can help pinpoint my problem, the first round is on me down at Hockeytown!
