For the past couple months my monte has been acting weird with the tranny. I will be coming home from work and I have to go up a pretty steep hill, once to about the middle of the hill my car starts to rev weird as if the tranny is slipping in and out of gears. ??? It now has started doing this when I am pulling onto a highway and around 45 mph it shifts into OD and it will do the rev thing and feel like it's slipping. I can give it more gas and it quits, but not sure what could be wrong?? Anyone else had/having these problems?? Any help is much appreciated!

Thanks!!

 

have you had a mechanic see if it might be setting any codes?

 

I dropped him off at the dealership today. Ball joint and tie rod end is getting replaced. I will call and have them see if there are any codes. Last time I thought it was my tranny it was really my MAF, but Idk what else this could be. I really hope it's something simple.

 

It could be low in tranny fluid, a vac leak, soliod going out...I truely hate trying to find out issues with this cars because it could be so many things it could be.

 

I just had my oil changed and they checked my fluids, everything seems fine that way. Had my tranny flushed last summer, only have driven about 5000 miles. Luckily, if it is a tranny problem my friend owns a transmission shop and only charges me parts and half of labor... Thank goodness for great friends, but hopefully it's something easy.

 

I got the tranny flushed in my 03 once n about 3months later was replacing a valve body

 

I've never had a transmission flushed, because then you still are using the same ol' trans filter. I ALWAYS pan drop. In my area, I change trans fluid/filter at LEAST every 100,000 miles.

My '94 Grand Am got it's second trans fluild/filter changed over summer. The Monte I may do next spring, not because of mileage, just age (has barely over 60,000 miles on the car).

 

Yea, I don't think they change the filter when they do a flush huh? I'm praying it's nothing serious.

 

Hope its something fairly simple for you!

 

It could honestly be a failing Cat.

Grab your Vin and mileage and call a local dealer about the cat replacement for 01 Montes.
