2008 Impala auto trans only goes in reverse

You either need to change the throttle position sensor or the gas pedal I got a 2008 Impala I had to put a new gas pedal in in so it would function properly

Hi, have you tried changing the oil filter? Or check the selector where it goes directly into the box, otherwise the selector inside the "brain" of the gearbox is knackered. Unfortunately the only way to fix it is virtually a full rebuild but I'd definitely check the filter first. Regards, Neil

redux. (A/T trans answer not STICK SHIFTED manuals)
no years stated
no transmission stated, auto or stick.

stuck in Reverse.
linkage checks are first.

the trans has lever on the side
called the Manual valve.
it that lever does not go to DRIVE,
then there will be no drive.
there is a cable from the Shift selector to that
transmission side lever.

inspect these parts for proper movement
no damage, not slipping cable, etc.
only you can do that.
or your mechanic.

The linkage to the trans may be bent

well first you want to make sure the linkage is tight it might say its in drive but on the trans it might not be pushing the lever and or if electronic faulty sensor also check fluid color is it bright reddish if so thats good if its really dark and smells burnt probably somthing internally wrong you may also have clogged trans filter

ur vehicle is in limp mode[ a safe mode ] which will get u home trying not to cause any damage to engine --theirs a few reasons the vehicle will do this-low oil pressure-transmission problem-have vehicle scanned most auto stores such as auto zone / advanced auto [check ur local area]do this service for free the code gives u a start point towards resolving ur problem

Sounds less like a transmission slip as a rear end issue. What exactly happens on the turn?

It should say on the Donut Not to exceed 35 Miles Per Hour. It is OK to drive on, Just make sure that it is Properly Inflated and you do not go too Fast as it will shred the tire and you will have a Bigger Problem!

If the jerks that stole your radio forced the shifter back, the linkage to the transmission (cable) is probably screwed up, or the shifter too. I assume you had no trouble before this incident. Also check the trans fluid level (warm up car and check according to instructions in your owners manual), although I'm sure it's screwed up from the morons that stole the radio. sounds like a job for the dealer or a body shop. the cable is probably out of sync w/ the shifter. Do park or reverse, or low gears work?. You may be able to save a few $ by checking the auto junkyard for the parts you need. good luck! countrycurt0
