Griner Trans Brake

I did find some instructions on line. They also said to remove the accumulator. The separator plate covers that spot. I haven’t hooked the T brake wire to the switch. First and reverse go into gear fine. Second and third not so much. I drove it up and down the driveway slowly and i can hardly tell it shifts. I would think that with it running full line pressure that it should shift pretty hard. Next week I’ll run t down the highway to see if it’s working properly. Right now I’m pretty disappointed. Kim
