ya this is gonna sound bad. i just rebuild my 89 n/a and i put it in earlier today. i just got the radiator and hoses bolted in and started to fill it. i got about a gallon and a half in when i heard splashing. i got under the car and the fluid seemed to be leaking out of the bottom of the transmission?!?! wtf did i not plug or what is going on?!? i thought i was just about done too!

not necessarily the bottom of the trans. more on the bottom where the trans and the rear iron meets.

 

There are a couple places I'd check. First would be the nipple on the drivers side of the rear iron that gets connected to the cabin heater core (nipple thru the firewall). Second would be the drain plug for the engine coolant, which looks like one of the drivers side engine mount bolts (mount to middle iron), except longer. The third would be the nipple on top of the rear iron that points straight up and would normally be connected to all the coolant lines that run to the BAC, thermowax etc.

 

This a manual or automatic transmission?

 

thanks. it was the nipple on the top of the rear iron.
