Well, I finished my TH350 to Muncie swap last night. Everything went really slick. Had a bit of a problem geting the tranny to slide in the last 3/4 inch, but once I took a break and checked on this site I learned the trick to push the clutch pedal in a bit. After coaxing my 3 year old away from Scooby Doo to help me, it slid right in. The tranny is an M-20. everything inside looks great, it runs out smoothly, but first and second gear really whine. Is this life with a 4-speed? I've never run one before. 3rd and 4th are quiet, everything shifts fine, but 1st and 2nd whine. No grinds, clunks or anything else. and actually 2nd whines louder than first. Please tell me it's normal and just drive it!!!!

Hey I did the exact same swap with my '69. As far as the whine goes I can hear a vague one in both first and second and not in third and fourth. But then again its hard to hear a whine from the transmission over the whine of the supercharger.

Sounds like my M22. Gears on the M22 were cut strighter and the tranny was and is known for its whine. Are you sure of what you got?

All the numbers on the case check out to an M-20. I'm pretty sure it's been rebuilt though. perhaps it was rebuilt using some M-22 parts???? Another noise I've discovered is at idle. you can hear the tranny spinning, and if you press the clutch pedal in the noise stops. I'm assuming it's normal to hear it spinning like this. All these new noises when you're listening so closely after the swap are spooky.

Any time a tranny is rebuilt, it stands the chance of having gears replaced. You look at it from the rebuilders standpoint: You have several trannys with one laying there that needs 2nd. gear. You have a used gear on the shelf , or you can go buy a new gear ($175) and put in it. Which way do you think he is going to do? The majority of the time , it's getting a used gear, and it's going to whine. Their train of thought is: "Well, he might run Flowmasters, and he won't be able to hear it anyway. " Nothing wrong with the gear, just that it was ran , and meshed with the other gear in the other tranny.The reason for the whine is, it doesn't have the same clearances with this new tranny's gearset. How many rings on the input shaft does it have, and what P code and case are on it. The gears from a M-20 and M-22 don't interchange. It is a normal thing, so just drive it.

It is full of 90 wt. gear lube??? Also, excessive bearing wear will cause noise in lower gears and more so in reverse. Not a big deal under normal driving, hard use with high HP might cause problems though.

guys, yall have just let me fall back to 1978 when i had my first muncie.MAN was those the days,what i would do to hear and feel that whining again.that does it i,ve already got a dam* good turbo 350 bolted to the motor for my 69 i,am restoring but it,s going on the aution block.I,AM NOW IN THE MARKET FOR A MUNCIE.
