Here is what i typed up for them concerning my car:
Problems with 4l60e in 95 Camaro
Engine: 3.8L V6
Rebuilt at: 077455 Miles
Brought back in for 10-day inspection/complaint about vibration at: 077471 Miles
Problems:
First off, the second time I brought my car in for a test drive, a hole mysteriously appeared in the drivers seat. (possibly from a mechanic with a screwdriver in his pocket?) the tires were scuffed showing signs of spinning the tires, and grease was all over the interior.
Transmission has recently developed a leak, made sure fluid was always on full mark. Transmission slips between 2-3 shift and 3-4 shift at 50% throttle or more under load (entering highway is when it is most noticeable) Brought the car back in for a test drive, told absolutely nothing was wrong, problem recently reappeared, only more noticeable.
Occasionally, the trans shifts late from the 1-2 shift, once again was mentioned when last brought in and told absolutely nothing was wrong with it.
Transmission vibrates around 2000 rpm under load (when accelerating) mentioned when I brought it in for the 10 day inspection, and was told flywheel was bent, had flywheel replaced by Cottmans, and vibration persisted, was told idler pulley was bad on engine. THE VIBRATION DID NOT START UNTIL THE TRANSMISSION WAS REBUILT! The engine has no misfires/dead cylinders, and otherwise runs smoothly, vibration is only felt under acceleration.
Transmission only has ~8000 miles on rebuild. Transmission is not abused, and yet it is already slipping. I also have reason to believe that the vibration has something to do with the rebuild since it started when the transmission was rebuilt, and never had any hint of the vibration before it was rebuilt.
I have talked with a few people who are ASE certified in automatic transmissions, I was told that the vibration feels like a bent input shaft (he rode in the car). I am also a certified mechanic in engine repair, brakes, engine electrical, and hvac.
The onboard computer has thrown trouble code P1870 which is listed in GM service manuals as Transmission Component Slip, yet i am told that is nonsense and that my transmission is not slipping.
I have been very disappointed in the way this transmission has performed. I am very close to reporting this to the Better Business Bureau, and other agencies including, but not limited to the local media.
