If you already have the transmission removed, you do not need remove the pump from the case to replace the seal. even if you do suspect there is some debris that fell in there, I doubt you will find it. a hammer and long thin screw driver should do the trick getting the old seal out, you might be able to get a seal removal tool in there.
Also, be aware if you choose to remove the front pump, you will need to replace the front pump gasket, the large o-ring that goes around the bump body and the washers that go on the bolts that hold the front pump. It is also recommended you use the 2 alignment pins when re-installing the pump to the case. you can do it with out the pins, but it makes things more difficult. (been there, got several T-shirts... )
If you choose to remove the pump, there are 2 threaded holes in the front pump, which are used in conjunction with threaded adapters and slide hammer(s)
once you get the seal changed and ready to install the front pump;
**Make sure you replace the front pump gasket and o-ring before you re-install the pump **
Lubricate the rubber o-ring with vaseline or transmission assembly lube
tighten the bolts in a criss-cross manner and torque to 18-23 Ftlbs
I have looked at a lot of pumps. I have NEVER seen one that didn't have two threaded holes to pull it out. It looks like either you need to look harder, or scrap this trans because it can't be disassembled.
I just replaced my front seal last week. I did not remove the pump. I used a funny looking T tool and that worked like a charm to get the old seal out.
One reason I did not remove the pump is that a tranny-shop guy told me the parts would begin to fall out of place once I did remove the pump, and then I'd be in for a whole lot more heck once that happened.
Also, my truck did the same thing, it spit oil out a couple times. I pulled the tranny and replaced the front seal (because it was pouring out the rubber cap, like most others). In my opinion, the front seal was not bad (until I used that tool!). I personally think these trannys get hot, and then somehow blow it out the front seal. I installed a temperature gauge on my tranny, and have begun an experiment to see where the best place is to locate the sensor. Right now, it is in the test port (on the driver's side).
Thanks for the suggestion. I am beyond that stage,but stuck with another problem, due to my own stupidity.
I am glad I yanked the pump because the gasket (behind the pump was cracked. and the bushing was worn. Who ever installed the last seal split the metal on on it...
I have the transmission in a garbage can with the bell
housing sticking out the top so parts falling out are not a problem.
I had no front inspection plate or rubber plug in the transmission for the last 21,000 miles I've owned it. It came without those options. The inside of the Bell housing was very grimy.
I found the 2) 3/8 x 24 threaded holes inserted 2) 2 &1/2 inch bolts with flat washers and got the pump out using a crow bar carefully a little bit at a time from each side the pump came out pretty easily.
When I pulled the pump out there was some sort of a gasket behind it that resembled a plastic spray paint can top with a hole in it and two tabs on one edge floating around loose.
I put it in a "safe place" so I wouldn't lose it. Now I can't find it. I don't see it in any parts blow up and don't know what the SOB is called.
How is that for stupid?
So now I'm stuck on stupid and running out of money on rental cars.
