overdrive

Apologies in advance if this question has been asked and answered. I looked and didn't see this specific issue. I recently had a jasper automatic transmission put in my '98 3500. This weekend was the first chance I've had to really drive it and test it. Hooked to an enclosed trailer with OD OFF...

1996 Dodge Ram 3500. Automatic. Problem -Not Shifting into overdrive. A while ago sometimes the truck would not shift into OD and other times it worked fine. While messing with it I found that while driving down the road and it would not shift into OD I could put the trans in neutral , turn off...

A couple days ago my wire harness caught on fire but it only burnt the wires going to the two big plugs on the driver side of the motor. I butt spliced them all together just to get home. Now my speedometer, oil pressure and overdrive don’t work(overdrive I know it’s too working because the...

I want better mpg out of my 03 dually. It’s kind of embarrassing but I pulled my camper over the weekend and only got 10mpg highway (although wind speeds were high, 15mph+) Anyway I wish my 48re had one more gear so I think a GEAR VENDORS would help greatly. But guys at work are telling me EFI...

The only thing significant that happened between this morning and evening was a 30 minute hurricane of a thunderstorm but I don't think it has anything to do with the problem. I was able...

Hey there, no OD or LU, got dash code #37- [Open or short in CKT wiring or connectors. Voltage out of range at transmission temperature sensor input.] I've heard you can cross cross the wires with a 700 ohm resistor. Is this true? I tow for a living and this thing does not like hills. I have the...

I have a 92 Dodge diesel and I am having problems with the speedometer bouncing, and it wanting to shift down out of over drive. Does anyone know anything about it? Or also have this problem.:confused::(

OK I've got a 1998 2500 with the auto transmission, and just yesterday morning the overdrive quit working. We ran it the evening before and it worked like a charm, start it up in the morning and head to work and it will not shift into overdrive. I unplugged the wires going to the overdrive off switch...
