Got the Radix installed, and the next item is the shift kit. I have the Transgo HD2 kit, with corvette servos, and billet overdrive servos. Jag performance recommends using 2 washers, but that's without any pcm adjustments to line pressure. The transmission doesn't seem to shift hard at all on the tune that came from Magnuson. I was thinking about going with only 1 washer, instead of 2. What are everyone's thoughts on this.

 

joe and sheri at jag have put together a slew of radix trucks and built even more trannies to hold the power.

 

Yeah, I know that. They have been more than helpful in my purchases. I was just wondering if it might be better to only use one washer, instead of two, being the Magnuson tune does increase the line pressure some. I don't want to bang shifts.

 

well you can always throw in one and see how it works. one should be enough. but two will hold the pressure to shift better.

 

I did not install any washers in mine it still chirps a nice 2nd gear with the Vette servo, 2 washers would probably bang to hard IMO.

 

I put one washer in mine, and its a little firmer then what I would like at the low to part throttle shifts. The part throttle 1-2 shift is the first thing anyone notices when they get in my truck. I've got the vette servo and only drilled the 1-2 feed hole to .083. I'm thinking of taking out the shim, but we will see when I get some more miles on it. The WOT shift is great though, no slipping nice and firm and a little chirp.
