I have a 2000 ram 1500 4x4 slt with an auto trans. Its kind of awkward, I bought the truck for $1,500. It needs new outer door panels(rusty), but it runs and drives fine, except when your foots on the gas pedal theres one spot about 1/2 way floored where the pedal stops. You can floor it but it takes alot of force, but until that point it shifts perfect around 2,500-3,000 rpms through all gears. But when you romp on it, it wont shift back down into lower gears without banging and wont shift up unless rev'd reallllllyyyy high like 6k rpms. Like i said odd problem, I'm not too troubled. I consider it my gas saving problem lol, I dont drive the truck far and it has plenty of power at 1/2 throttle.

 

probably a couple different things. First thing I would look at though is the TV cable. Sounds like it might be binding.

At WOT, the trans pressure sensor gets over-saturated, and sends incorrect signals to the PCM.... so, it doesn't wanna shift. You can replace the sensor, and governor solenoid with borg warner HD parts, and solve that one.

 

My throttle has a little hard spot but it's not bad and shifts fine.

 

Clean the iac sensor on the back of the tb.

 

I'd check and see which cable is binding, TV or throttle. If you feel it when the truck is not running, disconnect the TV cable and see if it still does it. If it does it then most likely the throttle cable is bad. Disconnect it from the TB and check it also move the TB linkage manually and see if it's the TB itself. I wouldn't let it go, a stuck throttle is no fun.

 

Thanks everyone, I'll have to crawl under tomorrow n check it out, n when I mean hard spot I mean literally stomp on it get it past that spot
