How do I correctly identify which transmission is in my truck? I am not sure if it is a 47re or a 48re. The truck is the one in my signature. Production date= 1-03. codes in glove box = DGA and DG8.

I believe that is a 48re. I had to look up my brothers one time and those codes sound familer.

I believe a dealer can tell you with the VIN number and the other codes in the glove box.

48re

48re

I looked again its a 48re. DGB and DGP are codes for the 47re.

Thanks for the information! This forum ROCKS!

Does the 48RE circulate fluid when it is in PARK? I also found this link to be helpful. http://www.pacbrake.com/PDF/L5807.PDF

not 100% sure..but when in neutral..in my 47re anyway..it charges the converter...when i start mine in the mornin..especially in the winter time..i let it idle/run in neutral to let the fluid circulate.
