When ever im out driving and get the need to floor it whenevr the rpms get between 4 n 5 it will almost liek idle there untill i let up off hte gas and hten it switch...answers please

also... while idling in park or n if i give it gas it will go to about the 4 and then will almost choke and chake and not go anyfarther..


help please!!! lol

While in park and neutral, the vehicle has a rev limiter of about 4k RPM so you dont blow your engine.

While at a run, I would say it might be time to change your tranny filter. That is almost like the valve bodies are sticking. I would wait until someone else has a chance to give their opinion on your shifting issue.

check the color of the fluid... your tranny might be saying good bye

Either that or you need a new catalytic converter? When it gets to the high RPM's does it just stop accelerating?

no.. when im driving and hit high rpms it will jsut stay reving in those high rpms and not swich gears. alomost like its not keching the next gear

What speeds are you hitting? If you are just cruising up to those speeds or going WOT your shift points are different. So you need to know which one and at what speed it is supposed to shift to see if it is actually a problem.

Iirc a stock PCM under WOT won't upshift until approx 5800 rpms.

I was wondering the same thing, when i am sitting still i can only rev to 4k, i thought it was a problem. What does WOT mean?

Wide Open Throttle..

Balls to the Wall!

i kind of have that problem too, i will rev to about 4 or 5K and then let off and it shift into a neutral type thing and i can rev it again to about 3K rpm and then it will like pop into second? Idk but i had the tranny rebuilt a couple of years ago, i dont think it is messed up again. I think that im fine but idk, am I???

As per the revs in P and N its the rev limiter, but ur High RPM hold while driving ..yah Tranny forsuretake it in and get a flush, but I would change filter first, if that does not help, look at the price of a new tranny, or a rebuild

Not a flush, no!! Just drain and change filter and refill with new stuff!

Not tryin to step on toes but I wopuld recommened the flush, will remove dirt from valves and torque converter. It is said u dont even have to change filter when u do a flush..I dont agree, but the new fluid is pushed in the system backwards. U can also add a BG cleaner and after the fluid change add a BG softshift.
Just my insite

Nice,

These trannies do not like to be flushed. Unless it's a regular service. On higher mileage 4T65s 9 times out 10 a flush only makes things worse.

That's why we always recommend just a filter change.
