Iv'e seen alot of talk about differant trannys. How can I find out what tranny is on my truck. its unchanged from the factory. 06 Bighorn 4x4 quad cab

 

48re if you have an auto

 

You're just going to have to introduce yourself and ask his name.

 

G56 if its a manual.I bet your refering to some of the DIFFERANT REBUILDERS that hop up the 48re for more h.p. The only 4 speed automatic offered is the 48re.Then theres a fair amount of CUSTOM 48RE builders for high performance applications but its ALL the same basic unit.The 07.5 up are now a 68re in the trucks(6 speed)and the cab and chassis comes with a Asien(spelling)? 6 speed auto.

ok so the first number in 48re obviously correlates with the number of gears it has. whats the other number and letter denote?

 

That is funny!!!!!!!!!!
I'm sipping a jack and coke, it was alittle slow to kick in .

 

E is electronic shift.

 

its a 48RE

 

4 - number of forward gears

8 - relative duty use based on a scale of 1 - 9

R - rear wheel drive

E - electronic shift management
