I have a 72 4door Lark, th350. Not running when i got the car, rebuilt the engine, a bit over 500 miles on it. I was pretty sure i didnt have 3rd gear, installed a tach. No 3rd. I had a Trans leak, and when low i had a delay shifting to reverse, 4 seconds solid. Also i have never managed to get the kickdown, detent cable hooked up. i recently dropped the trans, replaced pan gasket, filter, installed a Trans Go shift kit, replaced the modulator, front main seal. Could the kickdown cable somehow be causing my 3rd issue? Any tips on getting it installed? Any other thoughts on 3rd gear failing? The car shifts fine 1st-2nd. Runs about 4k rpm at 70. Trans is still out, likely installed tomorrow or next day. Then i will know if i have 3rd and see if i got the leak, the only thing i skipped(leak wise) is the pump seal.
