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.

Transfer case snap ring failed second time in 89,000 miles. Makes grinding sound from stop as gears clash. Can avoid major damage if accelerate very slowly. Snap ring is a $2 part. Labor is about $150 to replace snap ring. $700 to repair transfer case if internal damage.

Worst problem is in differential - it makes a sound like airplane ready to take off - can't believe that a 4 yr. Old car can have this happen - have spent well over $5,000 since I bought it - really upset !
