Herzog Motor Sports

Don't do business with Doug Herzog. I paid $1,900 for a 350 turbo transmission it started slipping the first three months that I had it installed. I have a transmission cooler on this daily driver classic of mine.The transmission slips and doesn't work. One time Doug offered to tear it down and work on it for a fee.STAY AWAY FROM THIS SCAMMER.

Doug rebuilt my TH350 transmission and rebuilt and strengthened my 10 bolt rear end back in Feb. 2024. I finally got the car back on the road and both work great. The transmission shifts firmly and works just as I had hoped. The rear end was setup perfectly, no noise or issues. Doug is very knowledgeable and rebuilds everything quick, usually in just a few days. I am a very happy customer. Thanks!

Doug ha very easy to talk to, and seems willing to help in any way he can.

Gave doug a call with a last minute issue with setting up some gears and he was able to get me fixed up just in time for my next race! Great guy to deal with! Give doug a call to help out with your hot rod!

Rebuilt my C6 transmission had to bring it back to him three different times only wants to make a quick buck slap it together with all used parts by the time he was done with it I could have bought a brand new transmission and not had to put it in and pull it out three different times just being honest don't waste your time he don't care about you or your time a professional transmission Builder shouldn't Miss wore-out bushings and seals those are $5 parts that he can't even replace
