    What a great M22. It was a perfect addition to my big block 71 Camaro. It works perfect and isn’t scared when I put my foot in it. I looked for the last 6 months for a seller I could trust and knew what he was talking about. I wanted a 4speed that would handle the 630HP and live. I recommend Jeff at Midwest Muncie to anyone looking for a great 4speed. It is everything he told me it was going to be. Very Happy!!

    Does your new M22 shift smoother than the original?

  3. Joe says:

    Yes it shifts better than any 4-speed I have had in the last 30 plus years. I have over 3K miles on it and have had not one problem, even have had it down the 1/4 mile 8 times. Still shifts like the day I put it in. It has been the best investment I have made in my Camaro. Joe

    AWESOME PRODUCT WITH AWESOME SERVICE FROM A TOP NOTCH TRANNY EXPERT. THANKS JEFF!!! Very happy with my M22, fit, finish, and performance is perfect!

    Jeff, knew his muncies and got me hooked up with the M22. He also took mt worn out muncie for a trade in. Saved me a rebuild and I now have a bullet proof transmission. THANKS Rick

    Jeff sold me a M22 WR 10 Spline input, 32 spline output with the upgraded side cover. The whole way through Jeff promised me a high quality piece of machinery that could handle the torque of a strong Pontiac 400 or 455. The transmission was everything he said it would be and he was there every step of the way from my initial inquiry all the way to checking up on me after the first test drive. This is a guy who cares for his work and more importantly, his customers. I highly recommend Jeff to anyone who wants to do it right the first time. Thanks Jeff!

    What a great M22, I bought a Super Case wide ratio M22 for my big block Corvette. I had so many problems with the last two Muncie 4-speeds I bought from other builders. Now I have a 4-speed that shifts every time and can handle the big block power. Jeff answered every question and the wide ratio is perfect for the street/strip. I recommend Midwest Muncie to anyone looking for a perfect 4-speed. So happy to be able to drive my Corvette worry free. Thanks Midwest Muncie

  8. CC says:

    Midwest Muncie (Jeff) built me a M22 for my 70 BB Camaro. I could not be more happy with it after over 500 miles and it is only getting better. The customer service was excellent and Jeff asked all the right questions to build me the perfect 4-speed. Thanks again CC

    Didn’t think I would every have fun like I had 30 years ago with my 70 Chevelle. Jeff helped me with all the parts I needed to convert my Chevelle from the boring TH400 to a ass kicking original 70 M22. The M22w gears work wonderful with my 3.31 rear end gear. The low 1st 2.52 gear really get’s it cooking off the line. Midwest Muncie is the best!!

  10. 4spd Fred says:

    I do not claim to be a trans Guru but In the late 60’s early 70’s I was heavily involved in drag racing and had more then my share of Muncie M22s. The M22/Rock Crusher was rarely installed from the factory in production cars, If you needed one most likely you were involved in drag racing and making some decent power for the time. As a result most of these transmissions were modified, molested and tortured to death. I would start off a racing season with a couple brand new M22s, They would work pretty good for a while and soon id be changing gears regularly. We would go thru Countless clusters and replacement gears every month. By October Id have a couple 55 gallon drums full of destroyed gears. After a couple years I realized something, Once a Muncie breaks it will never perform as it did, Even when the case appears pristine and untouched it stretches and distorts causing premature failure of the gears. Id advise anyone thinking of installing a new set of gears in a blown trans to save themselves the trouble by buying one of these NEW super case M22s from Jeff.

    Hi Jeff, Dave in Chelsea MI with the 467 Olds 442. Just completed the install of the M22W super case you built for me last fall. I must say it is all I hoped it would be and more. This trans has removed all the driveline vibration I used to endure under heavy throttle with that tired old M20. I have been being nice to it during break in, I will give you more feedback once I throw some Olds torque through the system. It was a pleasure dealing with you and I appreciate the care and precision you put forth in your product! Thanks Again, Dave
