M22 or re stamped or counter exchange
 

I have a 69 L78 M22 with a 68 M22 In it I am thinking of getting a new M22 with a C code stamping .What would add the most value a 69 m22 from another Chevy ,a restamped M22 vin & date ,counter exchange, or a never stamped M22

To me, none of them make a difference in value because the original is gone….period.

If you to have to have something that looks the part, I’d go with a service replacement.

Me personally, I’d leave the transmission in there unless you feel that you have to change it, or if you found the original owner to that trans.

Depending on when the 1969 was built, it could have a 1968 assm date transmission, but you'll gain nothing from putting another wrong trans in it. the CT code trans is ok but I would just leave it as is, in my opinion......Joe

I would never use a restamp, as that would call into question whether anything else is restamped. A CT, (Chevrolet Transmission- what you are calling Counter Exchange) only adds value when coupled with documentation that it was a replacement for YOUR car. Otherwise it is just another transmission.
The only way any transmission adds value, is if your existing one needs rebuild, and you repair it or replace it.
If your non-original transmission is beyond repair, or if repair cost exceeds replacement cost, I'd look for a date-correct replacement first, and a CT second. But, in my opinion, none adds value.
If you can't sleep because you hate your current M22, then do whatever allows you to get some sleep. Otherwise, any replacement transmission will add cost without adding any value.

The A/B/C suffix was added during September 1968; early production 69s [approx. to N520xxx and L505xxx] will have a Muncie 4-speed without the code.

If you provide the first 4 characters of your VIN as above, I can provide some dates to fit your cars' build time frame.

Strike 'counter exchange' from your automotive vocabulary. It never existed; CE indicated a service replacement Chevrolet engine assembly. A service transmission was CT.
