99 ranger transmission not pumping fluid

[koths211]

I have a 99 ranger with 4r44e auto transmission in it... this is the 4th transmission that has been put into it. none of the transmissions pumped fluid out the lines to the cooler. blew air thru lines and cooler to make sure they are not plugged. what else could this be??? any kind of solenoid? please help me. truck cannot sit in grandparents driveway any longer...thanks.Ryan.

Are you installing the transmissions yourself?

On all automatics you have the front pump, this is the main pump for trans fluid, it is turned by the torque converter.
When you put the torque converter into the bell housing and into the transmission you have to line up the torque converter and front pump, they have slots that need to be aligned.
You turn the torque converter slowly while applying a little pressure, you will feel it click into place, keep turning and applying pressure, some automatics will click in deeper 3 times.

When bolting the bell housing to engine block they should slide together flush, you should NEVER EVER have to force them flush by putting in bolts and tightening them.
If you did then you broke the front pump.

Once bell housing and engine are bolted together the torque converter should slide forward slightly to be bolted to flex plate, if its pushed against flex plate and will not turn easily then something is wrong.

I did install it myself... and I did everything you listed.

torque converter was full...

in x3 clicks.

bell housing went right up to the block no issues.

pulled converter thru the flexplate to put the nuts on the studs

everything went together nice and easy.

im wondering if it could be a torque converter lockup solenoid or a

transmission pressure control solenoid

and are these hard to change?
