Advice on a new possible transmission issue.

Okay, about a month ago some rusty hose clamps gave out and my return hose for my transmission fluid became free. Basically dumped the entire contents of my transmission on the road. After replacing said hose clamps, adding 4 qts ATF, and a bottle of Lucas Transmission additive my jeep has been running GREAT for the past month. I even invested in the 5.2L v8 alternator upgrade (which fit and is running fine). Even stopped leaking ATF for the most part. Today (1-25-2013)...I've noticed that she's slipping but it kinda feels more like she's not shifting into first...(It's an automatic). I am due for an oil change this coming weekend but I feel like that is not the problem.

So my question is, Is the transmission on her last legs? How can I diagnose this? Any questions I can answer to help us get to the bottom of this would be fantastic.

4.0L i6, 191k miles on body, ~100k miles on the transmission.

Thanks!

Did you check the fluid properly to see if you are low? Even though you may have no visible leak the transmission cooler and radiator still share the same core. Could also be the governor pressure sensor if you have not had that replaced in awhile. If you have not done the trans filter replacement would be an opportune time to drop the pan and check the magnet.

So i put a new transmission filter in last November. The magnet was still good. New radiator as of June 2010. How can i check the governer pressure sensor? And what's the correct way to check fluid level? I put it in neutral while it's warm and check it then.

In neutral while on level ground while warm. Sounds like you checked it right. No way to check the governor pressure sensor without pulling the pan. They are notorious for going, though. Did you adjust your bands as well when you did the filter change?

running in neutral of course.
i'd check the fluid level again. 4qts isn't even as much as is needed for a pan drop, let alone dumping it all out the cooler lines on the road.

I don't know what to check for adjusting the bands. I have decent knowledge about my engine but transmissions are out of my league.
