Question : I have a 1968 Impala SS with a 327 and a powerglide. The transmission had the pan pulled (hardly any band-friction material in it)and a mild shift-kit installed. Although 1st,park and reverse are fine, the transmission won't shift into second and acts like it's locked into 1st (engine breaking on deceleration). The shifter and TVS linkages are adjusted properly and the vaccum-modulator "appears" to be OK.
Any help you could provide would be GREATLY appreciated. Thanks in advance for your time.
