So my boyfriends jeep is having a problem.
start it up, its fine. Runs, drives, shifts like normal.
After a few minutes the transmission loses power. The Regular amount of pressure on the gas petal, it goes no where. You have to really step on the gas to even make it crawl. Any idea of what is going on? Thank you in advance for any help.

(Fluid level is fine. No tranny leaks.)

First things first, have him check the transmission's ATF level. Low ATF can cause that problem. Set the parking brake, start the engine (!), then shift the transmission into Neutral(!!!). With the engine running and transmission in Neutral, check the ATF level with the transmission's dipstick that comes out from under the passenger-side firewall.

If the engine isn't running or if the transmission is in Park you'll get an erroneous ATF level indication on the dipstick. Also check the condition of the ATF... is it bright clear red as it should be and not smell burnt?

If it's low on ATF add ATF+4 via the dipstick tube, insert a small funnel into the tube so you can pour ATF+4 into the tube without spilling it. It's critical you only add ATF+4 if it's low. If the bottle doesn't say "ATF+4" in big letters on the front label it's the wrong stuff.

If your ATF level is up to the full mark, the transmission might have a bad torque converter or its bands need adjusting.

Edit: I see you just added the ATF level is fine but was it checked properly as described above?
