To add to this the 45RFE is actually a 5 speed trans since it has two 2nd gears.3rd gear is 1.00:1, 4th is overdrive. The 45RFE (2002-early 2003) has a .75 overdrive. The 42RLE (2003.5+) has a .69 overdrive.

Thanks for the answers guys
I am confused that when o/d is canceled engine speed drops 3 times from the start until reaching about 80kmph which suggests that the vehiche uses 4 speeds...
What do you think about the situation?
I believe he's referring to the engine speed (rpm's) dropping every time it up-shifts, and he seems to be seeing 3 up-shifts (2-3-4) even though it's not in OD.
Is this a CRD (diesel engine) by chance? Then you would have a 5 speed automatic, 545RFE.

you are exactly right about what I wanted to say,
but nope it is 3.7 not diesel
why I am obsessed about this subject is my transmission problem couldn't be solved for about 3 months.
at the moment, if I deactivate o/d ("O/D off" is turned on), transmission works well, but while o/d is active ("O/D off" is turned off) and vehicle needs to down-shift from o/d to 3rd gear an abnormal striking is felt and after 10-20 strikes (and strikes gets stronger) check engine light turns on and an error with the 4th gear ratio appears...
so I am trying to figure out the source of the problem, TCM or gears them selves?
Sounds to me like your O/D clutch pack is ******** the bed (for lack of a better term). Have a ****** shop hook it up to a computer and read out the CVI (clutch volume index) numbers. If they're out of range (Fundamentals or Forgetamentals Part 3 - Chrysler and Dodge | Search Autoparts <-- Ignore the part about the "dumb learn." Relearns are to be done by computer on these Jeeps.) then you likely have a problem with clutch material failing --> New/Rebuilt/Used trans time.
