Jerky Shifting

Hey!
2000 LT, 4 door4x4 here. Noticed that the truck is shifting really rough between 1st & 2nd. Just started tonite. It shifts, but it's a very jerky shift. Just had the tranny rebuilt inJune, still under warranty. Any ideas whwat it could be? Also, thanks for the past help. Everytime I had a question, I got my solution from Blazer Forum.com. You guys kick ***!

RE: Jerky Shifting

check and make sure fluid levels are ok. then if they are, take it back and tell them you demand a new tranny because yours shifts like crap.

RE: Jerky Shifting

It might just need band adjustment.

I would contact the place that built it for you and ask them.

Transmissions have a break in period, might be due for them to service it:
fluid change
filter
band adjustment

Could be just as simple as the filter needs to be changed.

I would have to agree with MNHawk that your best bet would be to have the shop that rebuilt it check it out...

Just thought about something else, when was the last time you checked the condition of the Mass Air Flow sensor, if it is really dirty it can make the tranny run funny since the computer uses the MAF sensor for some of its settings...
