Can I put a 4r44e from a 99 ranger into a 2001 ranger that has a 5r44e, both 3.0 auto flex

[Burnsy]

I understand one is a four speed, the 4r44e, and the other a five.....will the wiring /ecu etc be affected or need modifying? Thanks for any replies

Actually they are both 4 speeds, there is no 5th gear physically added in a 5R, OD is turned on in 1st gear to get a Faux 2nd gear, between the 4Rs 1st and 2nd wide ratios, and it IS technically a 5th "ratio" so qualifies as a "gear"
Very clever, these Americans

But nothing to do with your swap
No, you can't put a 1995 thru 2000 4R44E in a 2001 and up Ranger
In 2001 the automatics got an ISS sensor added which the 2001 and up computers needs to see, 2000 and earlier won't have it, so it wouldn't shift gears
Can't added one

Keep looking, try https://www.car-part.com/

Good site for local used parts, use your zipcode

Flex fuel or gas only doesn't matter for transmission swaps, just FYI

Thanks for the solid info....im now looking at a 2002 tranny from a 3.0 ....that should work, correct?

Yes, a 2002 5R44E from a 3.0l will be plug and play

Assuming both are for/from 2WD
4x4 trans are different


If you have never done an Auto trans install there is one VERY IMPORTANT thing you need to know

SEATING A TORQUE CONVERTER

Ford, Chevy, Dodge, any maker, its all the same
Failure to do this WILL break the transmission's Pump when you install it, and trans will never go into gear after that, full rebuild needed to repair
