My 1990 Buick Lasabre just drives backwards. It doesn't move forward. I think it is the transmission. I want to know if the problem can be fixed or if I might as well junk it. I'm in a budget. ($300). I will appreciate your answers. Thanks a lot.

For $300 you could probably get the seat turned around to face the other direction. That's about it.

Thank you but I don't think that's an intelligent answer. I´ve got a better answer at Google. I thought this was a serious place to get some advice like to junk the car or to try to fix it.

That was about as serious as you thinking you will fix that for $300.

Your reply is really funny but I think this one I got from other place would give me some hope. Thank you anyway.

Check it.
Transmission slipping and hard shifts can actually be caused by the computer if it is not reading the RPM correctly. Sensors can be easily replaced without disassembling a transmission, so this is the second easiest (and cheapest) repair that can fix the problem(s).detach the battery and let it stand for thirty minutes. Then, reattach and allow the system to reset itself. This usually takes around thirty minutes. If this doesn’t work either, then it’s time to take it to a mechanic.
I will try the battery advice and if it doesn't work I will junk it.

Yes, it would be if it was the least bit accurate. You have no forward gears. I seriously doubt that is an electronic problem but I'm sure our trans specialist be be along with his opinion.

The only thing electronic on your transmission is the converter clutch. That one uses a governor and vacuum modulator for shift timing. If fluid level and linkage is good, it has an internal problem. You might get lucky and score a 4t60 in the junkyard for $300.

Hello,
This trans should be a 4t60E, this trans has a 1-2 band that may be broken or your low sprag is no good, to fix this the trans will have to come out and come apart, this will cost alot more than 300.00 im sorry to say. If you have reverse this will eliminate your input clutch and input sprag as these are on in both foward and reverse. Gary
