2000 4.0L Ranger shifting rough.

[soadx85]

Hey everyone,

My Ranger has always seemed to shift rough when driving (automatic by the way), but lately I have the feeling the truck is shifting rougher then normal, the truck will slightly jerk when hovering around 40mph unless I stay under 40mph or accelerate through 40 to about45.

Anyway I don't usually drive that fast as I mainly only do city driving 20-35mph as with the cost of gas I just seem to drive to work and the store. I have noticed using "2" instead of "D" drive shifts much better, is there any downside to using "2" instead of drive for city driving?

I hope my transmission is not going out, I just had the fuel pump and air intake valve go out this past year.

Thanks for the help.

Driving in 2 keeps the truck in 2nd gear all the time. Slips the tranny more on takeoffs and will burn up gas if you leave it there at high speeds.

I am moving this to the transmission forums.

Well what about speeds up to 35mph? Will that burn up more gas?

Sorry about putting my topic in the wrong place.

Not only will it use more fuel, it will also tend to overheat the ATF and put more strain on the torque converter.

Go get the truck looked at. It could be something simple like a bad spark plug.

What ? !!!!!!!!!!!!!

Check the tranny fluid level, add if needed. Mine was having the same problem. I changed the tranny filter and fluid and even added lucas tranny additive. It was a night and day difference.
