corvette re/trans info
 

purchased patrially finished mcburnie conversion to 76 corvette. came w/ls6 and th200r4.

have converted to 4.11 re, (good launch in 1st, odrive in 4th w/lockup)

having trouble w/trans and speedo. trans is erratic, have installed shift kit and lockup kit from tci. still not good. have adjusted the throttle position cable from one end to another, 1 notch at a time. still no good.

would rather make this trans work, if possible.

also speedo is way off, (was 3.36 gear) any help with this also.
