Im assuming it's the 45rfe, am I correct

2005 QC ram 1500 auto 4.7L

 

yup, 45RFE

 

No, you have the 545rfe 5speed not the 45rfe which is a 4speed. Rams 2003+ all have the 545rfe tranny

Looky , yeah wiki is correct.

 

thanks for the help, just wanted to make sure.

 

45RFE, 545RFE, same tranny, different tuning.

but yeah, you do have the 545. my bad.

 

Only difference is software. You can turn a 45 into a 545 with a TCM change (on certain vehicles).

 

correct the 45RFE is capable of being a 5 speed with the TCM flash.

you have the 545RFE though.

 

Whaaaaaaaat? You telling me that if you have the 45, you have a 5 speed automatic that isn't using a gear?! Otherwise, how can a FLASH change from a 4 to a 5 speed? Someone PLEASE elaborate on this one...

 

I did find this thread, wanted to throw it out. I still don't understand how a TCM flash can add a gear, but I'm researching.

**wouldn't let me post the link**

 

its because this tranny is mostly electronic. a signal tells a solenoid where to send fluid and at what pressure, and depending on where/how it goes, it will engage a certain # of clutches giving you any given gear. there really arent mechanical "gears" inside the tranny. just a valve body, solenoid, and a bunch of clutch packs.
