AS most of you know the 124 Spider uses the MX-5 NC manual trans. I have a 2019 Abarth with 10K miles. purchased with 8K, that is a "little" rough shifting in low gears. I have read it's a common problem possibly solved by using a different fluid than the manufactures recommended type. Have any of you had the problem (it's not that bad but is noticeable) and is more noticeable than my 1980 TR7 manual that uses ATF. I know GM makes a manual fluid that is raved about but I have no experience with it. Any suggestions from you guys who have the most experience with this box (obviously)?
