automatic transmission problem :'(

huffa12 · #1 12-26-2011, 04:14 PM

Ok so my truck has been shifting hard into 3rd gear recently and today it started reving higher 2700 then during the shift to 3rd it goes all the way up to 3100 RPMs this is not normal for my truck and it only does this after i've been driving awhile and the trans is warmed up. any help?

Does it only do it when its warmed up? I know my truck started shifting weird, then after checking some things out also noticed the transmission fluid looked original after 70,000. Changed the fluid and noticed a better shift. Unfortunately I really cant think of any specific reason why a transmission would shift differently other than age.

If it is only when warmed up it means that the fluid is either dirty/ old and is not flowing properly. When was the last time that the Trans fluid was changed?

After reading your signature more carefully I realized you have the same engine/tranny. I went out and ran my truck around to the store and got it warmed up. I don't have a tach, but according to my SG-II I shift roughly around 2500-2800 depending on how much i'm pushing the pedal obviously. honestly, I hate the transmission they put in this truck. I got it when it only had 40k on it and it felt like it was already going out. Slowly began to realize this is just the way it shifts. I was so used to driving a stick that I'd forgotten how inefficient an auto can be.

Bright pink? Doesn't smell burnt?

there's a good pic at the bottom of the page. Sorry if this seems simple, just want to cancel out as many possibilities to narrow it down.

that's probably your best bet. if you're like me it will drive you crazy until you get a definitive answer. Best of luck to you!

Yeah just didn't think they'd charge me... Oh well when I get money in the bank I'll do a trans flush and filter change
