Rebuilt Tranny Startup NO oil in Converter

I had a guy build a 350 for me. He said he put about 1 Qt of synthetic fluid in converter and for me to do the fill through the dip stick when I was ready to start it up. Now 3 mo. later I am ready. He said if he put more, it just spills out and that it will be OK with the synthetic till it gets pumped more reg fluid in a few seconds from me filling it. Sound correct? How much do I put in before starting engine?

You mean how much tranny fluid do you put in before you start the motor I would just add a quart at a time until you see it on the dipstick, then run it breifly and check it again. OR......give it a little time and someone here with a bit more knowledge on trannies will tell you EXACTLY how much a 350 takes

The info you were given is correct.

Put 4 quarts of fluid in the trans before you start the engine. (Any more than that before starting the engine will come out the dipstick.) Add additional fluid while the engine is running until the trans dipstick reads FULL. Depending on how much fluid any trans cooler you might have holds and how long the lines are; the TH350 trans will hold 11-12 quarts when full. After filling the trans, shift the trans between all the gears to assure that you have circulation of trans fluid. Check for leaks.

Thank you. My other question is does it sound correct that there is only 1 QT in converter, I saw Jessie James in Irag and a guy blew the tranny by not filling converter.

A quart in the converter is just fine, it will lube the internals well. The converter will get pumped full as the pump begins to operate and you add more fluid. I suspect that the guy who ruined his converter started it up dry and things deteriorated from there.

The guy in Iraq broke the pump when they stabbed the engine, it did not break from no fluid. They did not show you that, they just let the little guy take the fall for that bogus no fluid thing.

You might want to cycle the shifter from reverse to drive a couple of times too. After you start the engine and are satisified it is fine, set the parking brake, stand on the brake pedal and put the tranny in gear once you see it is full.

This will help get the fluid thru all of the body and insure it is fully distributed. Then check the level again.
