high shift points/late shifts trouble staying in a higher gear

[miles5241]

my tranny seems to be shifting late or have to take foot off gas for it to shift and if i hold it and shifts way to late and revs way to high for my liking(3500-4000rpms every gear). also the speedometer is 10 mph off so i looked into replacing my vss but i dont wanna spend the money without knowing if it is for sure. i also read if your tps is off that could also cause it which theres a way to reset? if anyone knows it would be great!

Is your service engine light on? TPS sensor will do that on the newer trucks. Since the speed is off I would say the speed sensor could be bad or at least the wire to it.

Have you tuned the vehicle at all?

[miles5241]

yea the owner before me got it tuned for the cam he put in. but i have no info on where or what duration of cam he put in so i'm not sure what kind of tune he got otherwise. which is also a concern of mine. is there anyway to check the if the wire is working correctly?

[miles5241]

no service light also

oh and tps on the new trucks would be 96+ with the vortecs? cause i got a 95 tbi

This is a new problem or its always done this?

[miles5241]

its done it since i've gotten the truck. i just never got around to caring to recently with my this oil leak ive been getting concerned since i need this truck to live. its my way to work and school ect. the high shift points concern me cause if i give it no gas it still wont shift till 3500rpms and it really doesnt need to shift that high you know? unless i let my foot off the gas then it shifts. but if i give it to much gas it down shifts back up to 3000rpms+. its just a real annoyance and cant be good for the engine or tranny

I would blame the tune before hardware failure.

[miles5241]

yea i've been blaming it. i just wanna check for sure. i dont know where i can get it retuned in this area is why i kinda wanna check all possible mechanical reasons first
