Replying to: renegade0351 (Jul 31, 2006 1:01 pm) Sold it and bought a Nissan Titan.   Intermittent problems are the hardest to diagnose and evidently, these trucks are full of intermittent problems as identified in the Silverado/Sierra problems and solutions.....
#6 of 503 gmc savana van transmission problem by smbob Aug 15, 2006 (7:03 am)
my 1998 gmc savanna van has a tranny quirk. when you accelerate from a stop you have to let up on the gas to shift from 1st to 2nd. it shifts fine after that until you slow down enough to drop back into first.have driven it many miles with this problem but it will still drive anywhere and back. any ideas? trans has 147,000 miles Replies to this message: gwilliamson (Aug 18, 2006 3:41 am) smbob (Aug 18, 2006 9:16 am)

Replying to: smbob (Aug 15, 2006 7:03 am) it may be a sticky 1-2 shift valve. Try some trans valve fix from P.B Blaster. You may have to drive it for a while to clean up the valve body. I am a transmission rebuilder and have used it many times. Replies to this message: smbob (Aug 18, 2006 9:16 am)

#9 of 503 chevy '02 2500 hd hot tranny ? by hdguy1 Aug 29, 2006 (3:46 pm)
hi, i have a '02 2500 with a 6ltr. with towing package. i just had the transmission flushed at 30k,my mech. told me that he didn't like the looks of the fluid, he said it looked like the transmission had been worked hard for some time. also the fluid was very dark. i also notice that the temp guage for the tranny always reads about 200degrees when i'm towing, is this normal? do i need to install a bigger cooling coil? any help would be great.

#10 of 503 chevy silverado 2500hd no reverse by davech2o Sep 03, 2006 (5:41 pm)
I'm looking for a little info on my 4L80E trans that will not move when switched to reverse, there was a slight squealing noise when going from drive to reverse and then it stopped moving. All drive gears work fine, I read a page from alldata that it could be the sun gear coming out of the sun case. I would appreciate some kind of info.

Replying to: hdguy1 (Aug 29, 2006 3:46 pm) I have to agree with your mechanic....trans fluid at 30K shouldn't be dark or burnt smelling unless it has been abused.   I would say that the towing temp would be in the correct range, depending on the weight you are towing and the type terrain.   Do you just tow intermittently or most of the time?   What weight are you towing and in what sort of terrain and open higway or in city traffic?   Just to be on the safe side I would go ahead and install a bigger after-market cooler.

Hello,   Other than the obvious, what does the HOT TRANSMISSION error message mean from the D.I.C.?   Thanks.   Dave Replies to this message: kcram (Sep 04, 2006 2:24 pm)

Replying to: dave95348 (Sep 02, 2006 4:01 pm) If you've overheated your fluid, you need to get that trans serviced as soon as possible. The fluid has probably been weakened to the point where continued use can lead to trans failure (been there, done that).   kcram - Pickups Host
