Hi the tansmission is slipping in drive and overdrive but 1,2, and reverse work will have too rebuild like ideas on how much?

Sounds like your transmission or lockup converter is slipping. The slipping causes heat and it is downshifting out of overdrive as a built-in protection strategy. Get the transmission looked at ASAP before you get stranded because it's stuck in a downward spiral right now. The problem could be caused by a stuck solenoid, which is a relatively cheap fix, but the more you drive it like this, the more you're working toward a full, expensive rebuild.

sounds like its internal, like the reverse band, that applies the overdrive, or the clutches that apply when in overdrive, either way the reverse band and overdrive clutches work hand in hand, for overdrive and reverse... id say you need a rebuild or a junk yard unit.... :( sorry for the bad news.

Overdrive is a low wear gear?band but it still wears.
Gonna need a tansmission rebuild to correct. Your fuel consumption is gonna go threw the roof until its repaired.

its a 15 amp fuse under the hood has to do with tourqe converter or o2 sensor under the truck

Its possible you have a code stored in the computer to help guide you.

Its also possible its time for a rebuild. Someone will have to remove the pan to see if there is any wear on the clutches.

What condition is the trans fluid in. Is it brown and burnt.

If your not sure you may need to get it inspected at least to see if you have a code stored, We can only guess here not seeing what condition the truck is in.

Have the fluid and filter changed.

Mike...

you need a rebuild, your overdrive clutch is worn out. do not drive in overdrive until the trans is rebuilt.

This is the typical transmission failure on these. You need a rebuild. The 3/4 gears clutches are burnt up.

carefully check the wires for any cuts possibly the 1-2 solenoid if the trans was slipping b4 concider a rebuild but u can get these parts on ebay

It sounds like the reverse band is out of adjustment. Three things can cause this, reverse band, front clutch and the overdrive direct clutch. To test the band, drive the truck in manual low up to 25 mph. Then let off, if the transmission doesn't pull the engine down, the band needs adjusted. If the front clutch is the problem, 3rd gear will be act weird too. The only test I know of for the overdrive direct is to inspect it, so process of elimination will have to work. Hopefully the problem is the band, because you can pull the pan, service the trans, adjust the band, and be done. Any of the other problems and you are looking at a rebuild. Good luck.
