question about 4t60e shift kit

[douellette]

does anybody know if the guy that posted this is still producing these peice? or where i can these peices already modified? thanks.

 

Shimming accumulators is not a very good approach to making a shift kit, a shift accumulator only controls shift quality, and your only result is going to be very abrupt slamming into gear and possible cracking of the pistons or breaking springs, the best approach however is to study the hydraulic schematics of the transmission and to oversize the orifices that feed the accumulators. The rule of this is that if you are to double the radius of the hole of the orifice, you quadruple the fluid volume while maintaining pressure. Thus making the accumulator apply at a much faster rate with the desired quickness, without the loss of shift quality. IE: A very firm yet un-abrupt shift pattern will result. Now my plan is to supply the w-body crowd with modified spacer plates, where all the orifices are drilled out, a stiffer double spring set for the accumulator for proper durability, and an adjustable vacuum modulator. Many worry about internally failing the 4t60E, but the truth is these are a very strong transmission with the exception of the differential which can be swapped for the 4t65EHD differential, and the reverse reaction shell which when broken will result in loss of 2nd, 4th and reverse. I believe all of these components must be corrected before one throws in spacers into the accumulator pistons.

not that I've heard of

i wonder how hard it would be to make my own custom modified spacer plate? i dont know what holes i would drill though.
