Does anyone here have access to parts numbers I would need in order to change out/update the 1-2 & 3-4 accumulator piston/springs?

Also, while I'm under there I thought I'd see about replacing the speedo gear to correct the reading since I'm running a little larger tire than stock - how might one calculate or figure out how to do that?

Thanks,

Jamie D.

 

How hard do you want it to shift? If you want it to shift better than stock buy the stock ones for a 2001 5.4.(except the inner lower) If you want it really hard just buy the upper one (brown) and don't use a lower. All of the 2-3 springs are the same.
