Quick Transmission Question

Hi...will a 42RLE from a 2003 4x4 swap in to replace a bad 42RLE that's in a 2005 2x4? Any differences between the 2x4 and 4x4 trannys?

Also, if I could fine one, would a 45RFE swap in to replace the bad 42RLE, and again any differences between 2x4 vs 4x4?

Not sure if the trannys are different or if the 4x4 simply adds a t-case.

Thanks!

Just a suggestion, but maybe you should ask you question in the right sections as this does not have anything to do with a JK model Jeep.

2011 Sahara Tan Rubicon 6 Speed
TR HD17 Beadlocks, BFGoodrich A/T KO2 34x10.50R17, Teraflex HD Tire Carrier, and more to come...

yep.
OP probably will get better answers on the sister site, pirate4x4.com to that non-JK question.

partial answer, a 545rfe will Not bolt in place of a 42rle trans. while JK's did have the 42rle's up to 2011, don't know if they are the same as 2003 or 2005's...

They are not since in 2003 there were no JK's just TJ's and LJ's.
