Tranny trouble

Hello guys,Ive a problem with my truck...When i start driving,1-2-3 is fine but when it comes time to shift from the 3 to 4 its take a long time before shifting and the rpm is about 4000...And this w-e ive been driving for an 1h on the highway and i cannot go over 90km/h....no trouble from the motor but its look like the tranny wont go on the last gear...My brother tell me it could be the lock-up or the torque converter...any ideas?

Welcome to the forum


2008 Ranger with 4.0l SOHC engine will have the 5R55E automatic transmission
This is a 5-speed transmission

So 4th and 5th gear, both are not working?

This transmission is controlled by the computer it shifts gears based on driver input(gas pedal position), speed and RPMs, there is a solenoid(valve) inside the transmission for each gear, the solenoids open and close based on computers signal to them.
So you could have broken wires in the transmission or bad solenoids.
Could also just be a band adjustment is needed.

No, not torque converter or lock up issue.

Best bet would be to have it checked at local transmission shop, they can test solenoids with ohm meter to see if wires and solenoids are OK and also test pressure inside transmission.
They can also read transmission codes if there are any, local auto parts store may be able to do that as well.

You may want to look at your transmission fluid. Wipe the dipstick once or twice on a paper towel (white) and look at the color. If it's bright pink to a dark red then you're likely fine. On the flipside, if it's brown, you want to change it.
If it's black, or smells burnt, then that's bad news, especially if you find metallic flakes in the fluid.

Don't delete your cat. Your engine won't run right without it and it will throw a CEL.

With modern engines, the cat is designed with the rest of the exhaust system for back pressure, which the engine desires. By removing it or hollowing it out you wind up affecting the back pressure and your performance will suffer.

Keep your cats on. Not to mention it's highly illegal, and if someone finds out what you've done.... Well, you could get some serious trouble. Could.
