Valve body upgrade/ cant shift gears????
Whats up guys, I am posting for my buddy Bobafettm he is down at the dragon right now and his car just gave out. He cant shift gears, his car starts out if 5th gear and wont shift only goes to park neutral and reverse also the display doesnt show gears. Tried a reboot and didnt work.... anybody know the problem?

I know for sure its the clutch packs, I have the same setup and on my 3rd transmission within 3500 miles, Im working on a custom built transmission with a sponsor of this site. So there should be somthing available as an upgrade soon.If he would just like to rebuild the transmission have him pm me. I have access to clutch packs that are not available to the general public.To explain when the clutch packs go out they disolve and get towrn to sh@* that in turns clogs the transmission oil filter thus loosing presure to the valve body thus you can not shift and no gears are available. I f you let the car sit for awhile somtimes and I mea somtimes it will clear the filter and you will be able to drive for about few miles if that and it will lock up again.
The problem with the 5at and high horse power is the input piston is not large enough to engage the clutch plates fully as well not enough preasure , but most people are trying to get around this by using a valve body but that only solves half the problem and creates more issues if the clutch packs are made of stock material which is almost like cardboard they can not handle the preasure and the force the small input piston is now putting them and you may fell some slipping at high rpm in one or several gears this is the sign that its going slippage beteen the clutch plates have occured and they start to tear each other apart.SOLUTION: UPGRADE CLUTCH PACKS TO HIGH GRADE MATERIAL----LARGER INPUT PISTION AND DRUM TO RETAIN IT---TEFLON BANDS-----AND VALVE BODY UPGRADE ---TORQUE CONVERTER LAST........

This is exactly what happened to me but I'm not pushing nearly that much hp. I'm at 310 whp. Getting an SGP VB upgrade and TC. Do you think that's enough or will I eventually need to get a rebuild with clutchpacks?
