42,700 miles on all highway miles, no hauling or towing. Anyone else had any troubles with new "hydromatic" trannies??? Replies to this message: iamlemko (Mar 18, 2007 3:08 pm) oomag12 (Mar 25, 2007 5:02 am) 07classic (Apr 01, 2007 3:14 am) paisan (Apr 03, 2007 6:38 am)

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 506 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)

#76 of 506 1990 GMC 1 ton, Clutch or Tranny problem? Fuel pump stays on.... by litalow79 Jan 09, 2007 (5:00 pm)
Hello, I have a 1990 GMC 1 ton truck, 454 ex-cab 4x4. We recently had a new-rebuilt motor installed and has MAYBE 300 miles on it. It had a new clutch installed as well... Now when I shift into 2nd gear it makes a slipping-whining noise, I dont know if I have a clutch problem or a tranny problem. The truck is low geared, so I mostly start out in 2nd gear. I have not noticed any problem in any other gears. The second problem is that the fuel pump will not always shut off when the truck is shut off and runs the battery down if I dont dis-connect it each night. Any help would be appreciated, thanks R.R.
