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.

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)

Replying to: oomag12 (Mar 18, 2007 6:57 am) With the tranny fried at 42,700 and GM's best offer is half of repair costs, it appears buying GM might not be to intelligent. They(GM)know the legal costs equal or outway the tranny, so their not worried there either. I honestly have been a GM person my entire driving career. But, you know Toyota might not be a bad choice.

Replying to: mrahn (Mar 21, 2007 4:53 am) My 06 silverado Z-71 has similar issues. When accellerating, I get a surging clear upto 60mph or better like the torque converter is slipping. It also acts as if I'm starting out in 3rd gear all the time. The only time it shifts worth a darn is when it's in tow mode.     This truck also has the 5.3 HO -12K on the truck and gas mileage has hit the floor. Went from 19mph on the hgwy to 15 max and maybe 10-13 in town.
#74 of 503 Chevy Silverado 1500 4.8 Transmission fix by catfish2 Apr 25, 2007 (5:47 am)
I posted here a while back about my Transmission bucking at between 55 and 65 mph, when ever I hit a small grade. It was the Torque Converter clutch pack. I did a total rebuilt swap. I then drove the truck to Florida and Back from Maryland. Top MPG was 20.2. Most though was 18 - 19 mpg. I was loaded down with drinking water and sodas and had the pedal to the metal. 75 mph most of the way. Averaged 66.4 mph. I think thats pretty good for a full size extended cab truck. It cost 2,250 at the dealer. Oh by the way, I have 195,000 miles on that truck and the fix came with a 5 year warranty. Thanks Jeff (Service Mngr.) from JBA Chevrolet, Glen Burnie, Maryland. You dah man. Replies to this message: lroshau (Oct 05, 2007 5:50 am) bumperdude (Oct 06, 2007 11:26 am)
