If I don't want to "hold 1st, 2nd, & 3rd to any RPM. You will also be able to downshift at any RPM. " do I need the spendier shift kit, what do the cheaper ones (40 bucks) do? If I'm looking for less expensive things to help it looks like I ought to replace the accumulator piston, servo, and throw on a cooler before worrying about a shift kit. Waddya all think?
then do a little searching. . .
