Just picked up a 67 LeMans... straight... clean inside and out... some say it has two extra doors but I like it... just got done going thru engine...sandblasting..painting..putting back together... puurs like a kitten... only problem is I cant go backwards unless I park facing uphill ... I know... poor me... Ive realised its a pain the the a$$ to try and find a 2 speed powerglide since most are used in alot of drags around here....anyone know some tricks I can try before buying a whole new tranny... already tried a new filter and such.... replies graciously accepted..... ty
