5-45rfe

 

yep, 545 its a 5 speed auto overdrive.

 

Thanks for the replys.

Somewhere I was told that it was a 5-speed but this Chilton's 2002-2005 says the vehicles covered in this manual are equipped with a 5 or 6 speed manual or a 4 speed automatic.

Next paragraph Chilton's says vehicles with an automatic transmission are equipped with a 45RFE or 545RFE, 46RE or 48RE four speed transmission.

So are they saying they just dont cover the 5 speed in this manual?
