shifting issues

goodlife1969 · May 1, 2015

Hey yall,I drive a 2000 Chevy z71 5.3. I just had my transfer case rebuilt and installed it in the truck this morning. Now I'm having a major issue with the truck not wanting to go higher than 2nd gear and every once in a couple miles it will shif t back into first with no power, almost like its in neutral. It has never done this before the t case rebuild. I went down the highway and before you know it its redlining and won't shift. I have never seen this before.. Any help would be greatly appreciated!

If you did the work yourself, go back under the truck and make sure no wires are caught up anywhere. It sounds like some of the electronic controls in the transmission are not working correctly.

Just checked. That's not the issue. Would it be one of the speed sensors being bad? Or not plugged in to the correct wire...?

You take it back to the shop that did the rebuild ,,, ,,, if it worked ok before .... Then they did something , ,,not your problem ,it's theirs !!!

If they took it out and put it in then their fault ,

Scanning it always removes guessing to a point ,,,,, cuz your SES light is on ... Right?

No there's no light. There was a service 4wd warning in the message center, but that went away after we unplugged the battery to reset the computer and it hasn't come back. Its at the shop now. Thanks yall

The message means there is a code as well as the light .

It's to bad that the owners manual says to "see your dealer if you get the message",,,, they don't explain shit

Yeah I know I hate it. I can't even find any other forums or videos of others with my truck having this issue. I just keep getting told to take it to a shop. It could be a thousand things and I've only checked problems 1-24 haha. Its all good, the shop I had the transfer case rebuilt at says they will fix the issue, and that it wasn't anything I did wrong when installing it. Hopefully its just something small like a bad sensor

Reading the post again I am thinkin that your 3-4 clutch has failed , oil level and condition is what ?

Ill have to check that when I get the truck back. I did check the tranny fluid right before I took it to the shop. It was at normal level but it appeared to be sparkly from small metal shavings but it wasn't black, just darker from age. Keep in mind also my father(the previous owner) didn't necessarily take care of it. I'm assuming its the original fluid from when he bought it in 02.... So u might be right. But I added about 4 qts of auto t case fluid to the t case so I know it's not that for sure. I'm prolly going to have the tranny rebuilt sometime in the near future but ill check on that again for u. Thanks for the advice!

T case holds 2 liters ,

4 qt is double , how you did that with a level plug hurts my head

Its what the guy at the tranny shop told me it took...I'm about to go legal with these ****s.... **** el Paso its nearly impossible to find a reliable shop around here...

But the level looked good tho so I have no idea either

Good thing about cases that use the fill plug to set the level of oil is that it is near impossible to overfill. Unless you lay the truck on its side with the fill plug pointing up that is.

Lol yea we did it on level ground and it took all of them. Idk its starting to confuse the hell out a me now

Perhaps the bottles were actually 500ml in volume instead of 1L?

Idk I just took the amount the shop gave me. But i should get the truck back tomorrow, will let y'all know the issue then just in case Someone else runs into this issue
