So my 1980 aircooled Westy is having some issues shifting in the cold temps (25 degrees F or lower). I just had a new/rebuilt transmission/transaxle installed last May with a new clutch etc. Could it just be the cold or do you think something else is messed up. I am not super mechanical, but willing to learn. Any real work would have to wait until the temps increase too. Thanks for any help.
