sspowr Posted September 4, 2013 Report Share Posted September 4, 2013 I posted up about swapping to a 6sp auto. It then dawned on me that it may not be the tranny itself that is the problem. So I decided to go a bit more into detail about my tranny issues and see if anyone has any ideas. 2003 Silverado SS. 6.0L, 4L65E. About 70xxxx miles.The transmission went out for the first time back in March. The truck was slipping all over the place, had lost gears (I forget which gears). Let it sit for about a month, and all of a sudden the trans came back and started acting pretty well normal, maybe a slight bit of slipping here and there. We took it on a 600-mile trip in May no problems. Drove it ever since, and it started getting very volatile, some day it would slip more than others, etc. Two weeks ago it completely blew up on me on the interstate, lost first and fourth (limp mode?) on the highway and I somehow got it home doing 30mph @ 3000rpms unless I forced it to upshift to third. It was almost as if it was limiting itself at a certain RPM, after that it felt like the tranny disengaged and the engine was just revving at 6000RPMs but no power went to the wheels. I tried driving it three days ago, couldn't get it out of the driveway. Reverse is still there but there is a delay before it goes into gear.Today I ran a computer scanner on it and all it threw was an MAF code.Does anyone have any clue what's going on with this truck??? I don't know where to start, I can't figure out why the trans came back and acted normal for a period of time when it was supposedly shot. Also possibly coincidentally, she had a trans oil leak around the time the transmission first went sour, and she was low, but I did not even have to put a quart in to get it back up on the dipstick.Thanks in advance for any replies!

Aldofashow Posted September 4, 2013 Report Share Posted September 4, 2013 A good start would be to clean your MAF and you could swing into a transmission shop with a scanner and have them scan the transmission Quote Link to comment Share on other sites More sharing options...

BlueAKSSS Posted September 4, 2013 Report Share Posted September 4, 2013 Unless your super low on fluid that sounds to me like your due for a rebuild. Sounds like you lost some clutches in the trans for sure, mine did a very similar thing when I lost the 3/4 gears. Quote Link to comment Share on other sites More sharing options...

sspowr Posted September 9, 2013 Author Report Share Posted September 9, 2013 Anyone have any ideas what may have gone in the transmission? Also, any reason why the truck is in limp mode but not throwing anything but an MAF code? Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted September 9, 2013 Report Share Posted September 9, 2013 No way in really telling until the trans is torn apart. Quote Link to comment Share on other sites More sharing options...
