high rpms but won't pick up speed

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

Nmmax16 what was the fix to your problem I'm having exact same thing going on

Could be mass air flow sensor. It'll also throw miss fire

What does it mean on an 04 Chevrolet Silverado when it won't shift into 3rd got first and second

OK I have a 2002 Chevy pick up four-wheel- drive I bought it from a kid who told me that it needs a transmission but she still goes in the first gear second gear and when she’s about to get into third gear the RPMs goes all the way up to 4000 RPMs and then she’s shifts and then she can only goes 55 miles an hour I change some sensors on it but it still giving me the problem the same problem so give me an idea doesn’t need a transmission or what

3/4 clutch pack is burnt out 100% positive it is ..same thing on my 01and 02 Silverado

Just bought a 2019 Chevy Silverado two days ago, the first day, one my way home from the dealer while doing 40 miles, the truck dip like when you shift gear fro third to second and the rpm when up to 5000 and them back to normal. The next day, while waiting for the light to change, the rpm went up and a surge came, lucky I had my food on the brakes,?if not I probably ran into the car in front of me. Well, I had the car only two days, is in then dealer’s shop for troubleshooting. When I explained what it was doing they gave the look like I was making things up. They drove it the next day and told that they cannot find anything wrong with it. I told them that they need to take it on the open freeway and not around the dealer parking lot. It sure enough, they took it on the open road and it happened to them, then they took the service manager and it happened again, them they took the dealer manager and it happened again.?after those test drives, they told they need to keep it so they can do some troubleshooting and it will Take few days. Now I am here without a truck...drive it only 19 miles

I have 2011 silverado crew cab sometimes when I'm on park ramp goes to 1000rpm then drops and picks up and recommendations

Check the fuel filter I had a 92 1500 that did something very similar and its was the fuel filter.

Does anyone knows the wiring colors position for this. White/black, Red/black, tan/white, white, yellow
