Thanks--finally getting it to a tranni guy tomorrow (not GM, an independent guy highly recommended)--it's my bread and butter so going a day without my BIG BLACK BITCH TRIXIE is hard. I'm HOPING that it is going to be that simple--I don't know when or if the fluid/filter was ever changed--I bought it with 84000 KMs and now has 91000 kms. I also read somewhere about some Lubegard (?) stuff that is supposed to work wonders on the shifting valves. I have not been able to find this stuff in PEI (Canada). Either way, I guess I'll just wait to hear what the guy says tomorrow.

93 shift problem by fgr8frk

I have a 93 2wd 5.7.
When driving on the interstate at 60 to 70mph, when I hit a bump in the road trans downshifts from OD and most of the time will shift back to OD but not always. And sometimes just keeps going back and forth in and out of OD. Any Thoughts, Thanks

hardwaregirl - It is upsetting when a new vehicle has a problem but consider this...GM sells 800,000 to 1,000,000 trucks a year. Even if only 1% have a problem right away, that's still 8,000-10,000 trucks with an immediate problem. Consider also that the truck has 1,000s of parts. Chevy will fix it under warranty. Hey, $&*# happens. I have a 2007 also, it went back in the first few days with a loose wire inside a rear door, power window wouldn't work. 20 minutes later it was done, I got 11,000 miles on it now and love it, no other problems. You have a 5 year, 100,000 mile warranty. Enjoy your new truck, relax, you and husband are going to love it too. The Silverado is a fine truck.

Transmission, Lock up torque converter issues ? by gregchp1
Sep 28, 2007 (5:12 pm)

2000 model 1500, Has no problems going thru the gears, but when it gets thru Overdrive and between 40-55mph tacking 1500rpm or so it will constantly change rpm by 200 up and down like the torque converter hits the final stage then changes its mind back and forth . Once you get above 55 it doesn't do it and runs fine.
Does the truck have a locking torque converter? Can you adjust it?

You haven't driven enough miles yet. My 07 Silverado lost the transmission for the first time at 17000 miles and for the second time at 28000. and at 36200 the normal steering shaft vibration that they won't fix because that is covered only up to 36000. But they agree that they never actually fixed this problem. They know there are problems with their trucks but they don't fix them. I had a 2005 Silverado that the 4x4 system was always showing service 4wd and putting itself in 4x4 when you start the truck. I kept replacing parts but the problem kept returning. I got rid of it and get a new one and now transmission problems. One more breakdown and I'm going to Toyota.

Time will tell, and if that happens to me I'll post. I'm not loyal to any car maker, esp. Toyota after numerous problems, service, & recalls I've had with them.
 
The term "lost the transmission" sounds sort of vague. What does that mean? What was the problem?
 
BTW, the 07 has been out less than a year and you have in excess of 36K miles??? Do you ever get out of your truck? Sounds suspicious to me.
 
Tundra is having trans problems too, in addition to other problems. Read the posts. Out of the frying pan, into the fire...

Torque converter locks at 39 mph and no there is no adjustment. Seven years later if it disturbs you drive in "3" until you exceed 45 mph

When you are refering to your 2007 please let the readers know if it is a 2007 classic or the 2007(new body style).
My tranny problem was at 7k miles on my 07.

Suggestion - from now on, the 2007 "classic" should be referred to as a 2006-1/2. That way there is no confusion between it and the 2007 NBS.
