What is the DIfference between "T" and "B"

The funny thing is, the "T" showed up on 05's and up.

Looks like in 04 they were listed as "B".

Could it be they fixed an issue in the 04 tranny, and needed to code the new tranny with the "T"

"The '04 transmissions had a planet retaining pin back out and machine away part of the trans. That was fixed mid-year '04. The early '05 trucks had a problem with a snap ring coming out of it's groove and exiting the transmission through the case. That was fixed mid-year '05."

Going from "T" to "B" could just be for updating/revising the trans... not sure...

I went into my Suncoast paperwork and couldn't find any info on this, the only thing I found different was the forward friction plates had two different designs, but it states that you wont know unless you disassemble.

Start by checking you hub bearings, axle u-joints, driveshaft u-joints, and carrier bearing.
