I put in a gearvendors OD last winter , so far I have to say it was well worth it

I've "heard" from other posts on websights that the GV unit has a harsh engage. is there any truth to that statement?

can one of you guys explain the shifting procedure on the dragstrip? where did u put the additional shift button? were u still using a shift light to monitor the shift points while using the g v overdrive ? passed this mod up, maybe later! thanks for any info------bob
