Car was stuttering, struggling to go. Was told by AAMCO we needed a new transmission. Had that done. But vehicle is still doing the same thing and they’re saying it’s a something to do with the fuel line issue so they changed a couple sensors (for free) but it’s still doing it. We have the car back, but on the drive home the check engine light came on. I’m feeling like we didn’t need a new transmission but it’s already installed and paid for but our car is still not running right. What should I do? Seems like they keep throwing parts at it in hopes it solves it. I just want it fixed.
If your in California look up BAR
AAMCO stands for All Automatics Must Come Out
My crystal ball says you got screwed but it is cloudy on what you should do… just as cloudy as the make model and year of your car.
Putting that one in my back pocket. Thanks
First off all, never go to AAMCO. Check the codes and get back to us.
Before you can ever diagnose a transmission, the car has to be running perfectly. I think you entrusted your car to monkeys.
Read up on mechanic laws in your area, that shop might owe you all your money back
They are never getting their money back, don’t even dangle that carrot. They signed all that away in the boilerplate a corporate lawyer provided to those ground level dumbasses at a franchise operation.

Did they replace the MAF sensor and O2 sensor? If not get it done or take it to a shop to get a real diagnoses.
I went to aamco once. They definitely fixed it. But it was only good enough to keep it going. Never went back to 100%. 3000$
Recalibrate the sensors by unplugging the battery, waiting some minutes (12 hours, depending on the vehicle) and plugging the battery back in.
Sometimes when batteries are replaced, the electrical “0” of the circuit with the olf battery isn’t the “0” with the new battery.
Lean code fuel pressure depending on year if it has external fuel filter start there

Hmm those transmissions aren’t really known for issues op. Did you change your fluids on time check for any recalls at first? 130k seems like a long time for no fluid change if that’s the case. Not doubting you op, but I feel like there is more to the story here. Did you tell you how they know the transmission was bad? Metal shavings? Transmission specific codes show up before they gave you the estimate for the transmission?
See we thought it was a fuel issue initially. Had all the plugs coils and injectors changed still experienced the same problem. Finally figured out it was doing the stuttering only under 2k rpm in any gear but as soon as it got over 2k it ran perfectly fine in any gear so we took it to a transmission shop. They said need a new transmission is needed. Changed it out and we took it home and we got halfway home and it started again. Took it back and they changed some sensors. Went to go get it and same thing happened. Issue is that it doesn’t do it until after you’ve driven it 10-13 miles from cold. Well yesterday when I was dropping it off at a different mechanic to get diagnosed I switched to manual to see if it was still the 2k rpm issue that we originally brought it in for and it is.
I dont know how relevant this info is but Ive seen the same issues on heavyduty trucks and machines. All tho they’re diesel engines but lots of times if the problem starts after a couple minutes of run time it might be caused by negative pressure at fuel tank.
You can easily check if thats the cause by leaving the fuel cap loose or off completely. What causes this could be blocked breather valve (not necessarily a valve, could be just an open hose to tank that allows air to flow in there.) Also you can check it by running the car with fuel cap closed untill problem appears then release the fuel cap to see if there negative pressure in there.
Its a long shot but might be worth checking. My knowledge on newer cars is really limited but those symptoms and codes could be related to fuelpump not getting enough fuel.
Car year make model? Miles
how could you even ask us this question without telling us what kind of car it is??
