Question about 2001 Pontiac Sunfire

Open Question

Car will not downshift sometimes....its a 4 speed auto transmission...I can floor the gas pedal but it won't shift to a lower gear, and not long after that happens the car just shuts off. You have to pull over and place in park and restart the car and it will be fine for awhile.Happened 3 times in the past 3 weeks.

SOURCE: when i drive my car i have to let up off my gas

I would check the transmission fluid, or take it to a shop and have them do it, a good parts store should check this for you at no cost! it may be low on fluid or it could need the fluid and filter replaced. worst case scenario you may need a new transmission if thats the case check local salvages ;)

Where is the passing gear on a 2003 Mitsubishi Diamante


'Passing gear' is a term that means the transmission is down-shifted to a lower gear (e.g., from 5th gear to 4th gear) for improved acceleration to pass another vehicle. There is no physical component called a passing gear in the transmission.
To engage the 'passing gear' with an automatic transmission should require nothing more than pressing the accelerator pedal down firmly. The transmission should downshift automatically to the next lower gear (sometimes it will downshift two gear ratios, depending on your speed and how far you depress the accelerator pedal).

1995 nissan sentra automatic trasmission will not go into passing gear


Gear shifts happen depending on how far the gas pedal is
pressed & the load on the vehicle

Transmission pressures change as you drive under different conditions,so the shifts happen at different speeds

There is no passing gear

If you have a 4 speed,you have 3 forward gears & an overdrive
forward gear, plus torque converter lock-up

You saying you have no 4th to 3rd downshift or whatever

Maybe the transaxle is failing mechanically inside-worn out

My 97 Saturn SL2 won't go past 30 mph. Even with


I guess my first question would be - are you saying it is slipping in 3rd gear ? If you push the gas pedal to the floor it should downshift into a lower gear.
If it is slipping, or not upshifting into 3rd gear, I'm afraid chances are the transmission is toast.
You can take it to a couple of shops for estimates but they will probably want to pull the pan and take a look inside.

Cable on top of engine broke on throttle what does it do


Replace the cable with one from your local auto parts store or dealer.
It may be for cruise control if your cruise control no longer works.
Or, it may be for the accelerator pedal.

Grinding gears from 1st to 2nd, 3rd to 5 ok


Either your clutch is getting bad, or you're shifting down too soon, and up too late. Try double clutching. Push in your clutch and push it into neutral. Release the clutch, fan the gas pedal, push the clutch again and shift into 1st. All this does is sychronize the speed of the transmission with the speed of the engine. There were, in the 60's, a lot of cars with the old "three on the tree" that you had to do this every time, and you get pretty good at it after a while.
