GMC Jimmy slipping problems

Windshield wipers do not work all the time. I was in a bad rainstorm last night and had to pull off the road because we couldn't see anything. Scary - this is a potential big law suit for gmc if anyone dies in an accident due to this common complaint. My gmc mechanic revealed that this happens on almost all gmc jimmy's, yet there is no recall to replace the defective part to date. Transmission - slipped badly. I paid to have it replaced and sometimes it still slips. This transmission repair shop said that this is common with the jimmy, as well as a faulty gas gauge, faulty ball joints and oxygen sensors. I did have to replace the oxygen sensor, but I consider that normal repairs.

Transmission slipping again...shift with gas pedal...let off on gas & let rpms drop to allow trans to shift. Dealership told me that they no longer service transmissions, too much hassle - will sell me a new one for $2500 plus labor @ another $900 to $1200...limited to only 6 months of coverage! I know of at least 10 other blazaer and jimmy owners at fort bliss that have had same tramsmission problems. An investigation should be opened to recall this transmission. I can be reached anytime at 915‑593‑5144 to further clarify my concerns...cpt burgess.

The transmission slips from 2nd to 4th gear and yet the 3 automotive shops can not locate a problem! Each one has replaced a part or 2 but they all say it is not the transmission nor the computer but none of them can fix it. I just keep getting passed down to another shop so they can get their $200.00 to $300.00 from me. The dealership I purchased it from will not even call me back to discuss the problem and I had paid an extra $1800.00 for an additional warranty on the vehicle. I will never buy another gmc again!

The transmission on my vehicle has been slipping-for lack of a better word-when it gets warm. It began at 50000 miles and the transmission had to be rebuilt-with gm parts at 85000 miles. It has begun to slip again. I understand from reviewing a site called complaint station that this is not an isolated problem.

The service engine light and diagnostics indicate internal transmission slip, while driving the vehicle on days when the temperature is above 80 degrees the transmission shifts harshly into second gear when started from a stop, when the temperature is below 70 degrees the transmission runs fine.

The transmission intermittently slips into, but not fully, 4wd when the vehicle is put in reverse. There is a very noticable noise that sounds like the transmission is not fully engaged. The only way to eliminate the noise is to shift the vehicle into 4wd and then back into 2wd. The vehicle has been brought back to the dealer on at least 4 occasions with this complaint. They have not been able to duplicate the problem and therefore have not done any research. On december 19th, 2000 the symptom reappeared after backing my car out of the driveway and I immediately brought it to the dealer. The service manager then test drove the vehicle and noted that the problem I described previously does exist and scheduled me to bring in the truck on thursday, december 28, 2000. When I brought the vehicle in the manager who had test drove the vehicle just one week ago did not seem to recall the condition and said they would check it out. I have a problem with the way the whole thing is being handled. I can't believe that my vehicle is the only one that has this problem in the entire country. I would think that gmc should have some information regarding this in their database. At this point I am not convinced that the proper diagnostic methods are being taken to locate the problem and remedy it. I don't know where else to turn and I am looking to you for any guidance that you can provide.
