The other day my 06 AUTO TRAN had a little shutter. It was in 2nd gear at around 12-15 mph and I do not recall the rpm but it was trying to shift into third. I noticed it again today in the parking lot trying to park. It does not show any problem when you really lay into it just when you are slowly accelerating around. Has anyone had any issues like this come up before? It just went over 34k the other day.

 

Is your truck stock? Have you ever had the trans serviced? If not have the oil/filter changed and ask about having the bands adjusted or checked. Good luck.

There is a TSB for the governor pressure solenoid valve in the VB, causes hunting and irratic shifts 1-2 under light throttle. Give DC a call before your 3/36 is up.

 

I'm having the identical issue and can't find the TSB.

I have done a fluid and filter change, but did not touch the bands.

Cool, is there somewhere I can find the writing to print it? It's not on Geno's and the one posted here isn't a link, so the formatting is off.

I want to have something in hand.

 

Thanks for the info, my truck is mainly stock the only upgrades so far is aeroturbine muffler and some PC XT AT 305's
