hello again.just writing to let you all know that we are currently going into production of our internal mechanical upgrades for the gm 700r4 AND 4L60Etransmissions.first part will be an e4340 output shaft for all syclone typhoon and 4 wheel drive vehicles.following will be an e4340 rear planetary carrier with pressure fed oil feed to the pinion shafts and pinion gears,e4340 reaction tubes,e4340 input housings,and others.those who are serious contact me as we will only produce what is in demand plus a few extras.products have already gone enough real world testing to validate their ability to perform in the true most extreme environments as our other products that preceeded them.let me hear some feedback and thanks to those who have supported us and understand that the foundation of ckperformance is based on our unique understanding of the inner workings of the automatic transmission.we also have produced another shift recalibration kit for this transmission based on information we gathered while producing our 2004r kit . i think that kit spoke for itself.thanks again kai pali yeia hara.
