Hey all,

I'm getting ready to do a drivetrain service and was considering putting in a Transgo Tugger shift kit, since I mainly use my truck to pull my toy hauler.

Anyone have/use one? Experiences, good or bad? If I'm running a 5Star tow tune am I going to have to have the tune redone?

BTW, it's a 2000 SD CC 4X4 with a 4R100 trans.

Thanks all!!!

 

I know some have used the transgo tuggers and say they are good kits, what about just swapping the entire valve body like John Woods, Riffraff Diesel: John Wood 4R100 Valve Body or Brians Truck Shop. I believe both will credit you the valve body if you come back to them for the trans later.

 

The Tugger is a great kit. I put one in my wife's 01 and it firmed up the shifts quite nice. You'll have to call 5 star and see how much they've bumped up the line pressure to see if they will need to reburn anything. The HD Tugger gives you an option of 3 different sizes to drill some holes that affects how firm the shift is. Maybe 5 star will have an opinion on which size to drill the plate.

 

Shameless self bump.

 

The tune will have to be changed. Depending on how picky you are it could take quite a bit of trial and error to get things dialed in. I had the factory tech accumulator on my truck. Basically Factory Techs similar version of the tugger kit but installed in an accumulator already. I removed it and went back to tunng only.

 

So if I'm already running a tuner, is there an advantage to installing the kit?
