RPM Drops

[aDroogie]

Hello,

This is my first post and I hope this is the correct area to do so in. Though to get down to it, I have a 2003 ranger, xlt 2WD with the 3.0. I am still new doing extensive repairs, and knowing what signs lead to, so after doing some research I feel I am left with no other choice but to post here.

Here recently when holding the gas pedal to maintain speed and doing minimum of 40 mph, after about 4-6 seconds the RPM will just drop about 500-700 RPM, after doing this if i press further down on the gas it hesitates for about 3-4 seconds then finally acts as though i re-applied the gas pedal and the RPM jumps and it picks up speed. There is no jolts or jumps with this happens, to passengers the cant even tell that something is going wrong. When the RPM does drop in order to resume maintaining speed or accelerate I have to completely let off the gas then reapply and it picks up like normal, once again no jolts or jumps.

I am really hoping this isnt meaning im needing a transmission overhaul but im not seeing many other options or people with my problem.

You should have the 5R44E automatic in there.
These have a "Controlled" torque converter vs a strictly "in gear" torque converter

It reads like the torque converter is being unlocked when it shouldn't be and then taking it's sweet time relocking when you accelerate.

Google: Ford 5R44E TCC problems

Yes, probably looking at a rebuild.

Ouch I was afraid to hear that. I'm still going through and checking sensors and anything electric I can think of, but I'm getting closer and closer to thinking a rebuild is going to be needed. Though I haven't taken my truck in to see if a shifting solenoid could be faulty. Thanks for the ideas though! I will for sure look into it.
