First, thanks in advance for your help.
After driving for more than 20 or 30 minutes, my 1984 Eldo convertible will not shift right. It feels like it goes from first gear to fourth, which is not good at 15 mph because it lugs, shakes, and can't get out of it's own way. It is also reluctant to downshift. It won't go from fourth to third or second. I have to throw it in neutral and then back to drive to get it to go back in first. Very frustrating, especially if I'm on the highway and then get off on surface streets. Chug chug chug all the way home.
Now, I'm pretty sure it's the transmission, right, or could it be something else? It's not slipping, it's just skipping gears. I also replaced the throttle position sensor a couple of months ago, so I doubt that's it.
Is it something simple I'm missing (doubt it, but hopeful)? About how much will a rebuilt transmission cost me, including labor?
BTW, the car show's has 131,7xxx miles, and I have no idea if this is the original transmission.
A picture is attached so you can see my Caddy convertible restoration project.
Thank you thank you thank you!
