Help! Replaced the 4eat and don't have any ATF flow.

elninoalex · #1 03-26-2006, 12:02 PM

What are the possibilities here? This is a Leg tranny into a Leg. I move the gear selector and the car doesn't do anything. I disconnected the ATF lines from the tranny and there is no flow with the engine on. If the torque converter drives the ATF pump and we know the TC is spinning, is it possible the circlip just popped out on installation? I suppose it could be a dead pump, but are there any other possibilities? I suppose there is no way to get this to work without pulling the tranny again. Has this happened to anyone? Thanks.

I don't know arything that would stop the oil flow, other that the pump not being driven by the torque converter. Did the converter locate into the pump OK when you fitted the box?

The TC seated properly. I actually don't know if the circlip was properly attached to the pump shaft or not. I bought it and installed it w/o checking. Would it not pump if the circlip was buggered up? I also forgot to fill the TC w/ATF before I installed it.

Was it a new or used torque converter??

It is the TC from the donor tranny w/80K.

I didn't see any ATF in it when I seated it onto the tranny.

I can't imagine no fluid being in the TC when it was just removed from a tranny and put on another one. It had to have fluid in it to work in the other tranny, and it doesn't just drain out.

I bought it from a Subaru parts yard. I don't really know how long it sat before I bought it. The TC in my bad tranny that I removed was of course full of ATF. But I don't recall seeing any evidence of ATF in the one that I installed.

hhhhmmmm. I can't imagine they would have drained it, But you never know.

Where's Tomsvx or svxfiles at on this one??

elninoalex · #10 03-27-2006, 10:34 AM

I put another 4 quarts of ATF(10 total) in it and it still won't pump. How long does it take to prime this system? I've let it run for about 4 minutes like this but nothing.

elninoalex · #11 03-27-2006, 10:57 AM

Great. I just found out the tranny sat in the yard for 5 years.

OUCH.

Well that probally won't help it any. Maybe mud dobbers filled the passages will dirt and stuff. God only knows what could be in there.

Did you pull the pan and change the internal filter?

Can you pull off the line under the starter (the one that comes from the front of the trans)and check the check valve, ball and spring?

SVX-FF · #14 03-27-2006, 11:44 AM

I agree with svxfiles. This is a simple check and you should always replace the internal filter with a tranny swap.

Not to make you look dumb but i have to ask if you installed the TC shaft into the TC before you installed it. This drives the pump, no pump/non flow. There should have been a noticeable clunk when the TC seats into the pump.

Also if the TC was not seated correctly and the tranny mounted to the engine you can break the AT pump very easily.

is it making noise?? I remember when I didn't line up the TC right for the first time.... Crushed the oil pump to death

I hope you didn't do the same
