Bought a auto overdrive kit. They tried to rip me off by not including what was promised. Tried to resolve it and went through a chain of cocky smart asses that told me I was wrong. E-mailed Shafty, no response. Filed a complaint with my CC co. Shafty the screw calls and agrees to send my parts if I pay and remove all bad posts. Install isnt as simple as they (and all the magazines they pay off) would like you to think. Car wont stay in first under hard acceleration. Spent hours and hours with phone calls and e-mails performing every test they could come up with. Replaced the wiring harness twice. Still has problem. They finally determine that I will need to remove the unit and pay to ship it back ($375 at my cost). If their transmision rebuilding company determines it a warranty issue they will fix it and ship it back. If not I pay to fix and ship back. Whats that old saying screw me once shame on you, screw me twice shame on me? These people are nothing short of theives. I cant stress enough how far anyone considering a overdrive should run in the opposite direction of these people. he lies cheats and steals with a big broad smile on his face. Oh and did I mention this shlub has filed for backruptcy. Just Google it.
