2005 Wrangler sport 6cyl and automatic. Ok im back posting about my tranny problems. I get the P0700 Transmission Control System Malfunction code. When I look it up seems right. Doesn't go into 4th sometimes and when I stop shut down the eng and restart it runs great until I stop at a light then wont shift again to 4th. Some days it runs great some not. I did find I have to get it from a dealer not a parts store. Problem now is I cant find it. Some pics show it behind the reservoir drivers side, some show it under the dash. I cant find it either place. A 6 by 6 metal box right? Help!!!
I think you misread my last answer... to clarify it, your 2005 transmission's ATF level can be checked in Park or Neutral. You checked yours in Neutral so if the engine was running and everything was warmed up while you did it, you're golden.

ok I have a question. I can do some mechanical work as long as its not rebuilding a tranny or engine. In your opinion is a code reader a worth the money? Probably is since I now own a Jeep, (Just Empty Every Pocket) LOL.
Napa and auto zone don't read codes anymore. Said the main office has told them they weren't allowed any more.
This just happened to me yesterday on my 04. Just before the start of a trail, I got a CEL. So, I drove around a bit and found my 42rle tranny locked in 2nd gear. Code p0700 on the odometer. Glad it happened when it did instead of the middle of the run. Very steep trails in Rimrock Wa where low gear is a necessity. We sent the group to have fun and limped my Jeep back to camp. Rats.
Anyway, now home and I need to fix it before the next trip. Hope it's an easy fix.
Is there anyway to tell if the TCM/PCM thingy is bad without buying them first?
Where are they on an 04 TJ X?
Thank you. Still learning about these computer controlled problems as I go.
As mentioned before P0700 is a generic code. It means that the transmission control system detects a problem and it is telling the ECM to alert you by turning on the check engine light. You need a scan tool that will communicate specifically with the transmission control system (not generic OBDII) to get the specific fault. Only then can you start diagnosing if it is a bad trans, sensor, TCM, etc.
I highly recommend to get one that reads live scan data, not just codes. I don't have any recommendations for you because my shop supplies professional level scan tools so I've never needed to look into the lower end models. I do know there are some for smart phones and laptops that are inexpensive, if not free, all you have to do is buy the cable to connect them.
Unless you get one that communicates with the Jeep TCM you still may only be able to read generic OBDII codes and may not have access to the trans code that is setting P0700.
Im taking mine in Monday afternoon. Ill let ya know what they say and how much!!! JEEP (Just Empty Every Pocket)
I was really having a problem with having to haul my Jeep to the dealer next week, just to have them hook up their fancy DRBIII code reader. No telling what the outcome would of been, or how much it would cost. Maybe I'm paranoid.
So today, I borrowed the TCM out of my buddies 04 TJ auto. BAM! Everything back to normal. All gears, OD, no CEL, everything. I put mine back in and it's back to limp mode and CEL.
I know my 04 has the TCM and PCM as separate units, unlike your 05. But, if you know anyone that has the same year and tranny as yours, it might be worth a shot.
All I needed to know was what was causing my problem. The part takes less than 5 minutes to install.
Good luck with your Jeep. Let us know the outcome.
^^That is very good info I didn't even think about.
Luckily for me the 04 has the TCM separate from the PCM.
Neither my friend's Jeep or mine has a sentry system. I checked after reading the above warning.
Since the OP's 05 TJ has the TCM and PCM as one unit, maybe he should just continue on to the dealer.
I hope my bad advice didn't cause any problems.
Clutch bearings for overdrive among other things $2200.00. Luckily I got the extended warranty when I bought it 3 months ago. $100 deductible. I can give you a more detailed report when I pick it up. I did find out if you have an extended warranty one of the first questions the adjuster ask is proof of routine maintenance. Repair guy said he has seen them refuse to pay if routine maint isn't up to date.
