Well, I tore the transmission apart today. It's super simple really. There are only two main shaft bearings, and as I suspected they were worn just enough to allow endplay in the shaft. That's what had locked my clutch up. For future reference, everything on the tranny is standard, but the...

NV1500 NV2550 TRANSMISSION REBUILD KIT WITH SYNCHRO RINGS FITS '00-'04 JEEP WRANGLER, LIBERTY & DODGE DAKOTA (BK494WS - The American Powertrain Warehouse This is the rebuild kit I am going with. I also ordered a new set of needle bearings. I will update this post as the project progresses.

Hey all, I own an '03 liberty sport, manual transmission, 4 cylinder motor. Last fall my clutch locked up on me right as I was pulling into my driveway. Some buddies and I pulled the tranny to install a new clutch (230,000 on the original clutch :sparta: ) and we found out the the input bearing...

Haha oops. I was reading this on my phone and saw "unplug". Needless to say, I was confused. Thanks for the explanation of the MAP sensor anyway! :Stupid Me:

Ahhh okay. But wouldn't that make the engine run lean? I don't want to burn up my plugs or anything else for that matter just for the sake of 1-2 mpg. I'm back to stock now! going to pick up a new filter tomorrow. I'm running some Marvel Mystery oil in my gas and a splash in my oil too. I...

What do you mean? There is an oxygen sensor on the throttle body, no? I didn't notice anything plugged up to my airbox. How do I unplug my filter? I've had some fun with the k&n experiment :whip:, it would be nice to get some higher mpg's now!

Like I said, the filter does seem to give me more power, but my gas mileage and who knows what else is suffering. I have only gone full throttle twice, that I can remember. I drive pretty easy most of the time. Thanks for the tips! I'll go back to the stock airbox and buy a new filter. Any...

Hey all, I was recently given a K&N high flow pod filter in great condition. My boss at work was going to throw it in the trash, so I took it and fabricated a semi-cold/cooler air intake for my '03 2.4L Liberty. I have more power, definitely, but my gas mileage has gone down to 25 hwy, 21...

Update: I took out the center console and the leak is where I thought it was. The seal at the base of the shifter tower is worn out. I shouldn't have any problem fixing it myself but I'd have to get a part and I don't know how rare they are. Let me know where I can start looking.

I was changing my oil the other day and noticed that transmission lubricant was smeared on the rear end of my transmission near the connection with the driveshaft. The leak is not at the driveshaft coupling though, it is at the base of the shifter tower. It doesn't leak when I'm sitting still...

Thanks for the advice!! Rockymountain: Really? It is supposed to be good for life? My hanes manual says it is supposed to be changed every 30k miles. Maybe that is only for ATF. That would explain why it has performed fine since my dad bought it 7 years ago.

I need to change the manual transmission lubricant in my '03 Liberty sport, 4 cylinder. I visited a dealer to get a price quote on the fluid, Mopar 75W-85, and found out that it would cost me upwards of $70 for just the lubricant. Is there a big difference between gear oils such as 75W-85...

Okay, thanks. I'll check that out. I have a four cylinder and I haven't checked to see what the transmission type is yet, but that probably won't matter.

What is the recommended lubricant for my manual transmission? I have a hanes manual but cannot find where it specifies this. I really need to change the fluid in both the transmission and the rear differential. Thanks!!
