Do I have Transmission Issues
Hello all, for a while i have noticed while accelerating on interstate (usually 3rd to overdrive) the car will accelerate, but my rpm stays at 1800 until I speed up from about 58/60 ish to 70. I have noticed this while driving on the highway as well. The trans also makes a thud and vibration while shifting drom 3rd to OD. I am wondering if my trans is slipping? Sometimes it even seems to shift in between 3rd and 4th if try to accelerate but if I give it more gas it locks into 3rd.

235,000 miles origional motor and trans. Yes the motor and trans probably need to be replaced, but it drives great apart from this trans issue. I am looking for a cheaper fix so the car will drive for a few more months
