Buick regal acting funny?

Question

recently my 2001 Buick regal with 103000 miles started to act funny during hard accelerations. previously when the pedal was put to the floor it would drop to a lower gear then accelerate accordingly. now though, it seems to stay in the same gear and just rev the rpms with hardly any change of speeds and it will stay at about 5000 until i let off. any ideas what could be wrong?

Answer 1

sounds like a tranny problem...But i would take it to a tranny shop.

But if you are mechanically capable or if you want request a tranny filter and oil change..

Good luck!

Answer 2

deff. sounds like either transmission trouble, engine computer trouble, or your TPS (throttle position sensor is not sending the correct signal to the engine computer which it should be sending (WOT) or wide open throttle when you floor it... then the engine computer tells the transmission to downshift for passing.. but then again you have to be going a certain speed for the computer to do this like under 60MPH because the computer does not want to damage the transmission

Answer 3

If your rpm's rise but your car does not accelerate your transmission is slipping.

Check the fluid first, everything after that cost a lot of money.

Good Luck!
