high rpms but won't pick up speed
When accelerating quickly my rpms go up but I
gain no speed. Going uphill I loose speed to where
I'm going 40 mph even with the gas floored
It sounds like your transmission is slipping. Have you checked the fluid level?
Yes Fluid level is fine it shifts fine if im gain Ing speed slowly but when I need to step on it or gain speed real quick then it gets to about 3000 rpm and won't go above 65. Would that still indicate slipping?
It doesn't sound like clutch slipping, if that was the case the rpms would skyrocket while your speed stayed the same. It sounds to me like your vehicle is in limp mode. If that was the case it would be throwing some sort of codes for sure and I'm guessing you would have a warning light.
My check engine light came on before I had that issue I was told at the time it was my catalytic converter had gone bad so I got rid of the cats. Should I have a scan run specifically for the trans?
I'm guessing removing the cats put you into limp mode. I have the same setup on my Audi but the tune I have codes out the O2 sensors so that the car doesn't do that/throw a code. If you clear the codes you might be able to drive it for a bit before it goes back into limp. If that's the case you'll know what's wrong. Im a self taught Audi guy so take all of this with that in mind. I know on Audis if you don't want to code out the O2 sensors you can throw a spacer in the downstream one so that it reads lower CO2 and thinks the cat is working. Not sure about your truck though sorry.
I have a 2001 Chevy Silverado ext cab and me truck go up to the 6000 rpm is it the 02 sensor or the crank sensor or the tranny
