What is the exact make and model of the 6-speed transmission that is in our trucks? Mine is a 2004 SRT10 Reg Cab.
Thanks for the help.

Should be a Tremec T56! Viper Version as there are many different T56 trannies. The Vette has one, Camaro and Trans Am has a different one, Aston Martin has a diff one, and a few select other manufacturers use them but none interchange really.

The Ram version is different than the Viper as well. Engineers beefed up the internals due to additional weight of the Ram. Also, the rear tail is different on the 04's versus the 05 & 06 i.e. vibration damper.
