94 2.5L Auto

So apparently its a big mystery for myself and everyone I've talked to so far.
Can anyone tell me or point me in the right direction to find out

1. What type of transmission is in my 1994 2.5L 3speed Automatic?
2. Is there a Fill and Drain bolt on the sides of my transmission that I would use to change out the fluid?
3. ATF+4 is the correct fluid?

*Someone told me my T-case is connected to my trans and they share oil. Witch is rediculsas because My T-case only holds 1qt of fluid.

*Someone told me I have an AX-15 because there in all YJ's but I looked at those and they all are 5 speed manuals.

*Someone told me I need to replace a big gasket to change my trans fluid but that docent make since if I have a fill and drain bolt?

PLEASE HELP ME!!

No help?
I don't have a drain or fill bolt.

I was thinking long and hard.
What would happen if I tried to pump out the old fluid by sticking the pumps tube down the transmission fill hole in the engine bay.

You should have a TF904 3 speed behind there.

The AX15 was included with the 6 cylinder YJ's from late 1989-1995.

The 4 cylinders got the AX5 trans up until 1994 when the TF904 was included for the 94-95 as an option.

The person that said you have to replace the big gasket is correct. On the bottom of the transmission you have a pan that is held on by several small bolts. loosen those bolts and if need be gently persuade the gasket to brake loose (be careful not to damage the mating surface) the fluid should start draining out. Continue to loosen the bolts on one end to tilt the pan and allow more fluid out. After most of the fluid has drained remove the pan. You will see the large flat filter. Remove and replace the filter. Put new gasket on replace pan and torque to correct specs. Refill thru transmission dip stick tube using a funnel. This should get a lot of the fluid out. It wont get out what is in the torque converter but this is a typical transmission fluid change.

When you get that pan off, take and put a drain hole in it. the parts store sells a drain bolt kit. There is even a recessed area that I would use to put the drain. This way you can drain the fluid more often since the filter is normally good for much longer time periods between changes.

So I tried to do this the correct way. Watched a series of very detailed videos on how-to. However the piping to my exhaust makes it extremely difficult to get a wrench in there to loosen the bolts closest to the front of the vehicle.

so I half assed it.

I pushed a fluid pump tube down the transmission fill tube and pumped out about 3 quarts of fluid, then added 3 new quarts.
After driving for a day and measuring the transmission fluid level (when the jeep was completely warmed up, in natural, like the dipstick says) It said I was short a pint so I added some more.

Do a proper siphon. Measure with string the length of the dipstick tube to bottom of pan, then measure to 12" above the ground to the top of the dipstick. Measure the diameter of the dipstick tube.
Go to local hardware store, get a clear tube the 2 lengths added together. The 12" above the ground is for a bucket to drain into.

Get electrical tape and mark the first distance roughly on the tubing. Put tubing into dipstick tube and the tape mark should be close to the top of the dipstick. Put the other end of the tube straight underneath. Get your bucket put underneath as well.
Go underneath and start sucking till the atf is past the pan level itself. The siphoning (vacuum) of the fluid will keep it flowing into the bucket.

When you are done. Pull tube out of dipstick, spray wd40 into it and let it hang over bucket to drain residue fluid out for overnight. When you feel its 'dry' spray wd40 into tube, put both ends together and put paper towel into both end to keep 'garage dust' out. Hang out of the way till next time use. Use can use water instead of wd40. But you'd be best to let the water run through it for a little time.
