Alright i think something is wrong with my tranny because when i get hard onto the gas it wont shift into a gear untill i hit 7K rpm's which is redlining so i normally let off let it shift then get back on it...

Also when im cruising at 70-75 mph my rpm's are right around 4K and this really doesnt seem right....

I just got the car about two months ago and I dont know all about cars but im not a complete idiot...

Does anyone know what either of these problems could be?

 

sounds like the throttle valve may be sticking ,

 

Actually, I know what both could be....

Your tach reads WAY WAY WAY high, like these always do when they fail. That's how they fail... they read high. I have about 4 or 5 of them, every one reads high except for the one in my car (or at least, it read right when I put it in there....)

See my signature for helpful advice on understanding multiple defects that seem to have some connection with each other.

 

I dont think the tach is wrong though because at idle its at 750 which doesnt seem high at all, but if it was the throttle valve what would i have to do to fix that

 

my tach is off in my iroc and it also idles at 750. i know because ive hooked it up to a scanner. my car at 3/4 throttle doesnt shift into second until 6000 rpm. the scanner showed a progressive increase in error as the rpms went up. nopw i dont know what engine you have but my 91 rs had the 50 tbi engine and it idled at 450 rpm fully warmed up(according to the tach and i firmsly believe that tach was in perfect order)

 

7k rpms? Like said above, your tach is off.

 

Imagine your tach has a 33% linear error. Your indicated 750 RPM idle then is actually more like a still-reasonable 600 RPM, but your indicated 7000 RPM shift point is only more like 4600 RPM in reality.

 

As said before, give your TV Cable a check.

 

His tach reads wrong when driving down the road. won't cause that. Therefore it is notbecause it leaves critical facts un-accounted-for.

Stick with that little truism right there; your life will be far more productive in the long run, because when something goes wrong, you'll go right straight to the problem, instead of wasting your time with a bunch of worthless and expensive "maybe it's this, maybe it's that" stupidity.
