Transmission Proublem When I put it in drive or reverce it only goes on the engian tourk. giveing it gas realy does not do much. But if i push my OD buttom it will go just fine in drive. WHY?

Could be a transaxle Clutch Lock-Up problem,
not OD

TCC Shutter -- Torque Converter Clutch [-- Shutter

If that can be resolved with a new selonoid
is questionable
Has to be diagnosed

Your light on the gas & in OD ,but the lock-up isn't
releasing when you slow down or put gas to it ,to
speed up

you realy need a hand held computer to erase trouble code,but what the tow button does is it locks the transmission so it doesnt go into overdrive while towing,you can manualy put shifter into drive ,not over drive

THE OD LIGHT SHOULD ONLY BE LIT UP WHEN THE OD IS TURNED OFF LIKE WHEN YOUR TOWING. WHEN TOWING YOU DONT WANT THE OD ON .PUTS TOO MUCH STRESS ON TRANS. UNDER NORMAL OPPERATION THE LIGHT SHOULD BE OFF...

Hi:) The best thing to do is take it in to a transmission specialist it sound like the 2-4 Band pistons on the right side of the transmission under that 3 inch round aluminum cap has lost it's ORing seals. When you put the shifter in OD does it start to move?if so that is normal or do you have to put it in 3rd before the truck starts to move if so you have a broken forward sprag and will have third but not fourth.And it could be a shift solenoid or valve in the fluid pan that operates 4 shift piston.

This sounds like you may be low on trany oil, start by checking the oil level in the trany, if its full then you may have internal problem and may need a rebuild. hope this is helpful.

Good chance there is a problem with the wiring to the OD solenoid or the OD solenoid itself. The solenoid is located at the top of the tranny, on driver side. Unplug the solenoid and put + 12-volt to it, if you hear it click in and out give it a test drive with your rigged wiring, if she goes in to OD then you know the tranny / solenoid are good but problem with OD relay, switch or heat sensor. Push come to shove you can just rewire it to a new switch and be done with it (that's what I ended up doing)

Please let me know if this assisted you.

Thanks,

The shift down linkage on the carburetor below the gas pedal cable might need to be adjusted to increase the hydraulic pressure on the internal clutch plates in the transmission it shows you how to do that in a car manual.

Hello. As you know, the transmission is one of the more sophisticated components in any auto. It takes the most transmission pressure to engage reverse, third, and fourth gear in an auto tranny. In an auto tranny, the shifter is connected to a linkage that manually shifts between the different gears in the transmission. When you shift into reverse, all transmission pressure is concentrated to engage reverse. When you shift to drive the transmission will operate normally, building pressure until it can shift into the next gear. With third, second, or first gear selected it will lock out all higher gears (Unless the TCU detects overrevving of the engine, in which case it will override gear selection and upshift to avoid engine damage). All the TCU does in a modern auto tranny is control shift points. Years and years ago, shifting was controlled by a spring attached to the gas pedal. When the gas pedal was depressed, the spring would expand. As tranny pressure grew, the spring would become compressed until it was fully compressed, engaging the next gear. The harder you stepped on the gas, the longer you went until the tranny shifted. In modern transmissions the TCU dictates shift points, and not much else. The TCU will also control when the torque converter will lock, but that's where it's duties end. The problem with engaging reverse is either a linkage issue, or a problem with the pump not building enough pressure to fully engage reverse.

Try putting the shifter in reverse, holding the brakes firmly, and giving the car gas. If the car reaches a higher RPM and suddenly slams into reverse it is the pump. The pump will only build enough pressure to engage reverse with higher RPM's. If the pump is severly damaged it won't engage at all, but if this is the case it probably won't engage third or fourth gear either at that point. If the problem is with the linkage, reverse just won't engage whatsoever, despite RPM's. I'd say start with the shift linkage. If it's bent or misadjusted it could cause reverse to not be fully engaged. The TCU doesn't control reverse at all, since there are no shift points and no need for the torque converter to lock.

do you turn it off ???sounds like the starter remove it and load test

all of these trucks do that
