Series of email correspondence with gm regarding the transmission replacement in my 1996 gmc suburban which failed after only 75,000 miles - 25,000 miles before the gm recommended service. Gm has chosen not to offer any assistance. I have found this to be a common occurrence with gm transmissions. 12/31/2003 08:37 am michelle, I had the local dealer install a new transmission last week. I asked the service technician why the transmission had failed. He noted that it had overheated and trash and debris were found in the fluid. He also noted that they, the gm dealer, recommend servicing the transmission every 50,000 miles. I follow the short-trip service schedule even though my truck is driven on the highway and not used excessively to avoid problems like this. According to the gm owners manual, the transmission should not have required servicing for another 25,000 miles. I follow and exceed your service recommendations. I now have a failure that could have been avoided more frequent service. Please help me understand. -----original message----- from: [email protected] sent: 12/23/03 10:08:53 am to: [email protected] subject: re: 1-172307605 I had a very good conversation with joe. Unfortunately, with his best efforts, he was not able to secure any assistance. I understand the transmission is out of warranty. I understand that there have been no recalls. What I do not understand - after speaking with multiple automotive professionals including several gm service and parts associates - is why this appears to be a common issue with gm trucks. I can also speak from my sister's personal transmission replacement in her 2002 z71tahoe. If the truck had been used for business purposes, had not been serviced regularly, or had over 150,000 miles - I could understand the transmission failing. Again, this truck has less than 75,000 highway miles and has been used for family travel.

We have a 1996 6.5 turbo diesel gmc suburban. We had severe stalling problems. The dealer replaced the fuel pump at their cost and installed at our cost, new glow plugs, glow plug sensor, battery, and battery cables suspected to be the problem. It continued to stall. We returned to the dealer and they replaced the pump again at their cost, but we had to pay to drop the tank to check for contamination. There was a deteriorated screen we paid to replace. It still stalled. Only this time it stalled when I was going 50 MPH and approaching curves along the river. I lost all power steering and brakes. Me and my five young kids almost ended up in the river. Had it been normal winter roads, we would have. All along we've done research and had it rediagnosed by a professional diesel mechanic, so we knew to tell our dealer (automall in brattleboro vermont) to replace the pump mounted driver (pmd) sometimes called a fuel solenoid driver (fsd). After problems where automall tried to rip us off for a fake $100 deductible, they will install it at no charge tomorrow (1/7/04). We have driven just over 1000 miles total. However, this does not fix the problem. From all the research we've done, weve discovered many people have reported the same dangerous accounts of stalling. Several report having almost had serious accidents like I had two days ago. According to research, pmd failures are the most common part to fail on gm 6.5 diesels. The pmd overheats because of placement near the engine. There is a simple, yet costly fix that consumers should not have to pay to be safe. A pump driver cooler (pdc) can mount on the firewall (not the engine) to move the pmd away from the heat. Please investigate and issue a recall to install pdc's on these engines so we can once again be safe in our vehicles. My family of 7 cant afford another stall, especially during these winter months, and new pdcs alone cant guarantee safety. Thank you.
