I've been having some engine/tranny problems lately, not really sure what the problem is though. It takes a long time switch to the next gear and when it does it revs to about 3 or 4 rpms and drops back down. This only happens when Im going about 30 or so miles and hour. I had my tranny looked at and he said its pulling, both in drive and reverse. He asked me to get my engine looked at. So I was going to get that done and while I was driving I had that gear switching problem again, this time I ended up red-lining and my truck stop driving. I cut it off and cut it back on and tried to go but it wouldnt go, it did however, go in reverse. When the tow truck came, one of the guys said that my back right wheel was locking up. When I got it to the shop he told me that my brakes where locked up and where gonna have to get a mechanic in here. My question is, what could of caused my brakes to lock up like that? Is this gonna be expensive?

 

Not too sure regarding the issues with the tranny, but I have had to replace my right front brake caliper twice now. You might try this to see if it's brake or differential / tranny problems. Jack it up and put it on 4 stands. Shift into Neutral, and try to spin the tire (by hand) that is stuck. If it still sticks, then it should be brake related.

Do you ever use your parking brake? If not, the cables can rust and then stick, which might cause the wheel to drag. Spray some PB Blaster or Deep Creep on the cable, work the parking brake a few times, and hope for the best. Otherwise, you get to replace the cables, and probably the parking break too depending on the condition of your pads.

I'd next take off the tire in question and look at your pistons & rotors or the drums. My pistons have seized twice now on the right front, but a master cylinder, new calipers, rotors, and pads, and I was ready to go. For you ( I think you have drums) you are going to have to take them apart. Check out Hayes or Chilton for the step-by-step on the drums. If you can, check your master cylinder for a fluid leak. If you see one, then replace it.

I'm not certain that this would cause your shift problems, unless the break on sensor does not allow the vehicle to shift. Good luck.

 

you mentioned it was your rear brakes and you have a 92 so the rears are drums....how long ago were the brakes replaced last? Its very possible the shoes are frozen to the drum, there are little springs in the drum the pull the shoes back into place when the brake pedal is released now these sometimes brake or rust and dont work anymore or just stretch, they should be replaced with every brake job its the hardware kit but they dont always get replaced to save a few bucks. Price wise depends if you have to replace the drums or not, you will probally have to do the fronts as well and you might need new rotors so any were from 200 to 600, depenign on what needs to be replaced. I had a similer problem on my 92 when i first hit the brakes i would her like a clunk and then the rears will lock up, took it to my mechanic turns out i was metal to metal on the drums had to replace drums and did a complete brake job fixed the problem

 

I agree with the previous post. Pull the rear drums and the problem should be obvious. It may take quite a bit of coaxing (adjusting and big hammer) to get the one drum off.
