automatic transmission not engaging

[blackdawg]

I had my turbo 400 rebuilt a while back.finally got everything in.the problem i"m having is the transmission is not engaging.I had a transmission leak from the line that was dropping a bunch of fluid.I have tightened that up as well as the pan bolts.the vacuam line is running from the modulater to a port on my edelbrock carb.the sensor which i guess would be for transmission pressure is not hooked up.I topped the tranny up last week and left it after chasing leaks.so this morning i will start the truck and make sure the level is up.what else can i check for if this thing doesn"t move getting very frusterated.truck is a 1966 chevy stepside with a 350 and turbo 400 with b&m shift kit.thanks

get one of those turbo 400 transmission books. they are invaluable. they have a great diagnostic/troubleshoot section. try barnes and noble or amazon if you want to get it.
but you are on the right track to hunt down your problem. it will always slip if you are seriously a leaker. also any vacuum leak to the trans will cause it to slip or not work. neutral switchs can problem sometimes. i assume you checked that linkage is working proper. closely inspect for any obvious problems.
