SOURCE: 2003 chevy silverado will not shift into drive or overdrive.

transmission shift solenoid is stuck open this is a common vehicle issue in automatics and not particular to any make or model vehicle 15 dollar part and arm and leg for labor if taken in

heres an idea to try
take out the transmission filter and replace with new one make sure to take not of any metal debry in trans pan this indicates the trans had sheered its gears down and a trans rebuild is needed
the transfilter needs to be changed at a certain milage interval they can get clogged up
there is a kit you buy for your truck at any parts store
its an easy change hour of time unbolt trans pan unbolt trans filter and put new one in
kit comes with new seals less than an hour you can do it yourself

to overdrive you would feel a difference in shift badley if it was that something to keep in mind

SOURCE: 4L80E trans. Lost passing gear/overdrive suddenly

Bad transmission, that's not a good answer. Bring it to the shop [so we can guess around], not a good answer either.

A good mecahanic will respond with something about the solenoids.

I have repaired the 4L80E on my tow truck, I have to do that almost every year, the last time it ran perfectly but when I push the pedal to the metal, it shifted from 3rd gear to 2nd and stays on 2nd gear until I turn the ignition off and start again.

The transmission was totally rebuilded so the answer "Time to rebuilt the transmission" is not acceptable.

I took it back to the shop and the mechanic replaced both solenoids A and B, that was the only thing that hasnt been replaced before, it was just a guess but works

So, I am not a mechanic but my sugestion is to replace the two speed sensors and solenoids before you take the tranny out of the car and be carefull who are you taking the transmission to because guessing is not always the best course of action

The two speed sensors are easy to replace, the solenoids are inside of the valve body but you may be able to replace them without removing the transmission from the truck

I have a 96 Chevy suburban and I was driving through the mountains and the transmission kept down shifting or slipping gears help?


Was it loaded with weight? Could have been overdrive. Vehicle should sometimes be dropped onto 3rd and left there under hilly conditions. So as not to shift too much. Suggest checking trans fluid level , possible trans filter change, or add trans cooler to keep temp down in fluid when in hilly terrain. Good luck.

Shift letters for a 1992 chevy 2500. what does each mean?


The D inside of an O is for overdrive. It is an automatic overdrive transmission. There isn't an overdrive button on it. If you want to disable the overdrive you have to shift down a gear.

I have a 93 Chevy Suburban 1500 and the Transmission won't shift into any gear. I have an 1983 Chevy Suburban Transmission that is still good. Can I use the 83 Transmission in my 93 Suburban?


Not without a little adapting. The 1993 has a 4l60e which is electronically controlled and has shift solenoids. If the 83 is an overdrive it is a 700r4 which is the same trans but not electronic. If you put it in the speedo wont work and you will need to install a T.V. cable so the transmission will shift. The 93 won't go forward or backwards?
