ok im trying to get my car back on the road and the tranny sucks. the trans is brand new from art carr and it shift way to soon. it will be in 3rd gear before 25mph. ive tried every adjustment on the linkage with no change. any help would be great. i know the only thing that was different from my other trans was the plug on the side is only a 3 prong on like the 4 prong but art carr told me that the new tranny has a internal ground or something like that and doesnt need the 4th prong. any help would be great. i wish someone would by this tranny from me and my other full built tranny so i can buy a real trans from PTS.
