#58 of 506 03 SILVERADO 1500 Transmission Problem? by catfish2 Mar 20, 2007 (4:30 pm)
Besides the normal 4.8 Carbon Tap, my Truck runs like a clock. 200+ miles a day. 19-21 MPG. I have 190,000 miles on it now. For the last 10K miles I am experiencing a violent bucking at between 50 and 60 mph. It seems to only occur when I am cruising along, with or withour cruise control, and hit an upward grade. If I hit the brake it eases up. It also seems to disappear if I go in to passing gear. I also feel a gentle bumping at idle with my foot on the brake. Could this be a Tourque Converter problem? Chevy wants to do a Tranny Swap $2, 500.00, but hasn't even checked it out. The Truck has been well maintained. Has anybody else had this experience?

#59 of 506 2006 GMC tranny by mrahn Mar 21, 2007 (4:53 am)
My Z 71 has 17,500 (+-)miles. Initially I took it in because it shifted rough out of first gear from the git-go. They reprogrammed the computer which did nothing for the shifting problem, but ever since occasionally when I start it up, it will be in four wheel drive. I have had it back two more times, the problem continues. I also am only getting about 14 mpg, and I drive about half highway miles. Something ain't right.

They know at that price, legal recourse by a single individual is not likely. Believe me, they really try to push you over the edge, they want you to go off and get belidegrent so they can justify denial of the claim. I did locate a salvage 06 trans with 2K for 1000.00 and its warranted for 2 years or 20K. I'm a lifelong GM guy, I have gone to bat for the brand countless times, but like the treachory of so-called close friend, i really stupid for it at this time. I let thier customer service folk know how i feel also. Thier CEO Waggoner, has corporate mission statement, that basically says Integrity and customer enthusiam were GM's top objective. What a joke. You can read it on thier site. I quoted him during negociations and i believe it helped to get them to cover half. Really, I don't believe i will ever buy a new GM product again.

Ive got a 96 Chevy 1500 that just rolled over 100k. Went to the store this morning w/no problemns. Came outgot in truck and went to back out and had the awfullest noise from the tranny.  It sounds like when your brakes are completely worn and grinding metal to metal. It does it in rev, 1st, and in o/d but not the other fwd gears. I drove it back home 25 miles and it doesnt slip and shifts fine, just has the noise on take off and when it hits O/d...... anyone had this problem before?

Replying to: bunn (Mar 27, 2007 6:42 am) The dealer doesn't usually fix transmissions, rather they send it out to a transmission shop locally who either repairs it or goes to the junkyard for a used one and overhauls it. So of the $3k you were quoted, a local transmission shop would probably quote you $2k to fix. Doing the math, I'd bet the Dodge dealer is charging at least $1k for his troubles.   Also figure it this way. What does a Dodge tech know about GM trucks?

Replying to: bunn (Mar 27, 2007 6:42 am) My 2 cents...Unrelated to this specific issue.    I would be very reluctant to buy a used vehicle from a competitive dealer (GM from Dodge...Ford from GM, Dodge from Ford...etc, etc). Seems to me there is a strong possibility the person that traded in the vehicle changed brands for a reason, such as losing confidence in the brand he had due to a bad experience (Conquest sale). I'm not saying this is always the case, but it would have me suspicious. Just thought I'd share my opinion on this.   I agree that bringing it back to the dealer to have the trans fixed is not the most economical way to do it, unless you are trying to get them to back it up and cover some of the cost. Once they refuse that, I would hightail it to the nearest Transmission shop and have it done by specially trained transmission technicians.

Replying to: obyone (Mar 27, 2007 8:59 am) A certified transmission technician on any product would be qualified to work on just about any automatic, they just may not have the experience dealing with specific problems. In my experience, most dealerships needing to have a competitive model's transmission repaired would send it to an independent transmission shop, or slip in a certified off-the-shelf rebuild.   On the other hand technicians move around. I wouldn't be surprized if a current Dodge or Ford transmission technician hasn't had a TG350, TH400, or a 4L60/80 apart sometime in their life.   Dusty Replies to this message: obyone (Mar 28, 2007 1:26 pm)
