Start clutch require special tools to replace?? The problem im having with my transmission is when i shift to drive cold or hot engine, the transmission would engage and jerk forward without me even pressing the gas. And it would pulsate. It would pulsate to the point that the engine will almost stall, this is assuming i press the brake on hard so it doesnt move. As far as accelerating, the engine has to rev up to about 2k rpm or so then it jerks to go. This happends in drive and reverse. I have pulled CEL and one is insufficent EGR flow, and i believe the other one was shift control something. I've already tried cleaning the EGR but no result for that. As far as working on the transmission itself. I've changed out my fluid twice. Previous owner did put regular ATF in it, but i put in HONDA CVT. Iv'e actually overhauled to lower valve body of the transmission also. and tested the solenoids. all seems too click when battery connect to it, except for the inhibitor solenoid with is a smaller different one of the three other solenoid. I opend the entire valve body and cleaned everything and made sure all the little valves moved freely. After doing all this i am about the start a ATX TO MTX Conversion, but i would like to get your input if i can fix this for cheaper.
Thanks in advance.

oh btw..when the CEL turns on the Drive light blinks, and if in driving in the city around 40mph or so it drives perfectly seems like. No slips or hard jerks at all. but if im on the highway and it comes on, the engine would rev like its in neutral
