  • 512957 - McLeod Muscle Car 5 Speed Transmission is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from First Full Season Complete and... Very pleased with the Mcleod 5-Speed! Swapped out my favorite Super T-10 for the McLeod trans which fit with almost no mods. I did swap out the trans mount with an adjustable unit because it was just a bit off, but I also have custom offset solid motor mounts. Also trimmed a little around the tunnel where the shift plate is for better clearance and then soundproofed around it. The speedo reversing gear unit was needed and works perfect. Paired the trans up with a new McLeod Extreme Street clutch kit then broke in gently for 500 miles or so, and then wailed on it for the next 2000+ miles. Never a whimper. By the end of the season everything was well broken in, and the shifting is now nice and smooth as butter. 80 mph on the expressway at 2000 rpm is a beautiful thing. The 2.95 first gear is a perfect match for a 3.55 rear if you like long burnouts in the moonlight. Vehicle is a 1968 pro touring style Pontiac Firebird with a 388 sbc which dynos at 562 HP and 521 ft.lbs TQ.

    Rated 5 out of 5 by from Outstanding Transmission and Customer Service I bought this for my 63 C10. I replaced a Muncie. So, the McLeod fits like a champ, no modifications of the tunnel, drive shaft, or even your shifter hole. With that regard, if the shifter hole doesn't line up, McLeod will make you any off-set shifter you want. It takes them 7-10 days to make it and costs $140. In my case, I had one made that was 1 inch forward and 2 3/4 to the left. That made the stick fall right where my former Munce stick did. Customer service: Freakin outstanding. I had an issue with the drive shaft going into the transmission. I called McLeod, they were extremely helpful. In fact, they gave me one of the owner's (I believe, or of some relation to him...) cell phone number and I spoke to him and he resolved my problem. I live in Columbus OH, Jegs delivered it to me the next day. Performance: Why didn't I do this earlier. Before the McLeod, I would turn 2800-3000 at 60-63 mph. Now, I turn 1200-1300. It makes the truck so much more enjoyable. I can cruise on the freeway and the motor is not screaming, I'm not getting passed like I'm standing still etc. Lastly, the shift is tight and smooth. It's a lot of money, I get it; however, I can't say enough good things about this transmission. I don't regret a penny of it. Hope this helps someone on the fence.

    Rated 5 out of 5 by from Did not just fall in, but a good fit Replaced an m22 with this trans. I had no real issues as my Muncie had the correct spline count on input and output, and did not need to change driveshaft length. Only issue was the trans mount placing the trans rather high, so made my own mount, but needed to add adjustable upper control arms on my differential to make the correct angles work. Shifter was no problem as I have no console and things JUST fit. Nice lower rpm at interstate speeds now. The speedometer cable reverse fit tightly but did fit. It mounts to the rear of the speedometer housing, and not to the trans...enough said.

    Rated 4 out of 5 by from Glad I went to a 5-speed in my 65 GTO The five speed just made this GTO able to run the interstate but this is not a bolt in and go. Modifications to fit include, cutting tunnel and rising about an inch. Shifter location changed to center and back about 3", this was no problem for me because I have no center console. Drive shaft needs to be shortened and a turbo 400 yoke. Stock trans brace worked but had to shorten rubber trans mount a little for yoke clearance Speedometer needs a reverse rotation adapter which I'm still trying to source out (The one Jeg's sells does NOT fit). Shifting was a little rough at first but has smoothed out and shifts nice now, glad I did it.

    is this tranny the same length as an m-21,also can i use the m-21 drive shaft yoke ?

    Asked by: ramshack
    No, the transmission is not the same length and the output spline is different so you will need a different driveshaft.

    Do you have the shifter in the top of trans configuration? I have a T-5 with lower higher ratio gears. Will i have to cut the input shaft?

    Asked by: Kalika
    This has a shifter on top, you can add any stick to get this in the position you need for your vehicle. This input shaft will work with most applications as long as you get the proper splined clutch disc.

    could you tell me if this transmission will fit in 1967 chevelle without cutting tunnel or dropping trans too far to effect drive line angles ? also is there a off set available for shifter to fit original counsel 2.25 " ?   Thanks    Stuart

    Asked by: scott327
    This should fit without modifications, but you will have to adjust the shifter stick to make it work.
