I just installed a b&m transpack along with a tci street fighter torque converter in my 4l60e. I put the trans back in and have all my forward gears and no reverse any transmission guys know what I did wrong??? any help before I take the valve body back off would be greatly appreciated thanks,

 

Im no tranny expert but I belive you miss installed a check ball in the VB. Either its in the wrong spot or you missed it all together.

 

I'm hoping it's something that simple. the kit says if you have reverse slippage or no reverse than it's either damaged or misaligned gaskets, or the snap ring on the pressure regulator valve isn't seated. I started all the valve body bolts before I tightened it down so the gaskets can't be off far enough to be blocking a hole, and I would think that if the regulator valve wasn't seated that it would be slipping or have no forward gears?? I'm just afraid I'll tear it apart and not see anything wrong. Any one else have any ideas??? thanks,

 

where are all the transmission experts, or people who have installed this kit at? I know there is someone in here. thanks,
