What oil goes into 42RLE/45RFE Jeep Transmission??

[Wagner]

Hi Guys.

Recently I purchase a Jeep Liberty 2006 V6 3.7L. Car is excellent. Only 58.000 km aged. Now it is time to change tranny oil. Here in Brazil is almost impossible to find MOPAR ATF +4 oil. So I took my car to Mercedes-Benz dealer. The German mechanic said: "for Jeep automatic transmission we use a German oil called Pentosin ATF1. It substitutes perfectly MOPAR oil. All our mercedes runs with that oil and everything goes fine."
I should believe the panzerman unconditionally but I think a good idea to listen other opinions. So, is the German correct???

Ah, before someone speak, Castrol TRANSMAX ATF+4® is not available here

Thanks for any advice...

A specific atf+4 not a multi purpose fluid

As far as I know there is no substitute for ATF+4. Im sure the Pentosin fluid is very good however it is not ATF+4. I have serviced many 42rle and 545rfe trans and the only thing I would ever put in it is ATF+4. Im not familiar with the auto industry in Brazil , is there not a mopar/fiat dealership there?

Any brand of ATF+4 should do the job. The 42RLE in there has a variable lockup torque converter, so I'd be careful about substituting fluids.

If you have to use an alternate fluid, try to find something that meets the Mercedes 236.10, 236.12 or 236.14 spec. Those have all been used in the NAG1/722.6/W5A580 transmission, which Chrysler filled with ATF+4 in their vehicles. Being that it works fine on either fluid, I'd assume the fluids can interchange in other applications.

Excellent fluid but I haven't used it or tested it in a Mopar transmission requiring ATF+3 or ATF+4.

If you use it, and there is any shudder/transmission confusion/limp mode/error codes.... then you'll have to change the fluid a 2nd time.

Find ANY ATF+4 or a full synthetic universal multivehicle ATF that claims ATF+4 compatibility.
