When I bought my Jeep a few months ago it shifted clunky. I checked fluid level and added a quart. The problem was solved.
98 TJ, 4.0 64,000 miles

A search for 'dirty IAC' and bad TPS should bring up a lot of threads for how to clean/replace them. A dirty IAC can be cleaned, it doesn't need replacement. A bad TPS must be replaced, it can't be cleaned.

|GoldenSahara00||I believe you can adjust the tv cable jerry mentioned because I think it controls idle when shifting. It goes from your transmission up to your throttle body control and is linked in with it. Maybe take a look there. There are some good threads in other forums on the subject.|

|Gorving3||My 2001 Wrangler 4.0 seems to shift unnecessarily rough/harsh from P to R or D also, but it just seems the engine idles faster than really necessary. When I purchased it new I asked the dealer if the idle speed could be slowed down a little like we did back in the good ole carbureter days if the idle was too fast. Was informed that stuff is all computer controlled and no adjustment is available.|

I replaced both Ujoints today and it fixed all my problems completely
Jerry I also got around to checking the tv cable a few weeks ago and if anything it was a bit loose not tight.
Thanks for all the help guys.

|GoldenSahara00||Added some ATF4 and it seems to have helped.|
|08-09-2011 09:55 AM|
|kfdjason7620||Yeah mine has no slack whatsoever in it so I think imma give it just a little, maybe move it 1/8" to start with|
|08-09-2011 09:53 AM|
|GoldenSahara00||Yeah I am gona try to mess with the cable a little bit too but It seems fine and just got worse over the past month or so, at least in my head... haha. So we will see. my tranny runs fine though I would like an external cooling unit. But us kids never get nice things.|
|08-09-2011 09:35 AM|
|kfdjason7620||But I realythink if you "play" with the adjustment on the TV cable, you will make it suit you, but I just don't know how to get the adjuster apart, I played with it a little but scared I was gonna break it and I've for the service manual on CD rom, just haven't looked into it yet|
|08-09-2011 09:32 AM|
|kfdjason7620||Well, just me, but I've never done a power flush and probably never will, but I just replaced my tranny in June, 115k miles, I found it was cheaper to replace than rebuild, but I did put a cooler on the new(er) tranny, friction plates came apart on the old one (years or being overheated) and be being oblivious! (I was in the mindset of "if it ain't broke, don't fix it") but I know alot about it now.|

|GoldenSahara00||I have only owned my wrangler for a year, bought it at 119k. So I don't really know when/if it was done. I have read that if it wasn't done at all in the first 100k, not to worry about it and not do it. and I assume the PO had it done before because the fluid looks and smells good, not sure if that is a good judge but its about the best I have to go off of. I don't really have the reasources for a flush and filter, and I want to do a full flush not just drop the pan if I a am gona do it.|
|08-09-2011 07:45 AM|
|kfdjason7620||And being you got your tranny on your mind, it wont hurt to do a filter/fluid change, or when was the last time?|
|08-08-2011 08:42 PM|
|GoldenSahara00||Okay, well its not 1/4 from from, its 1/4 from OK. its in the MIN. its about 1.5 inches from full so, I figure topping it off can't hurt. already picked up a quart so, gona pop a little in.|
|08-08-2011 11:35 AM|
|kfdjason7620||1/4 inch off full is fine, better to be 1/4" low than over full, and my Jeeps done what your describing forever, but I ALWAYS make sure I am completely stopped before moving shifter and I always shifter in neutral for about 1 second before going into drive and same for going from D to R, but it did it with old tranny (115k miles) and with new...er tranny (39k miles) I swapped in june|
|08-08-2011 11:16 AM|
|GoldenSahara00||I drove to town and got gas and came home to warm engine up, it was fully warmed. Pulled E brake, cycled through the gears, then Put in N. checked the tranny fluid and it was clear red and smelled like oil, no burn. It was about 1/4 away from *OK* on the minimum side, so I could probably top it off some. ATF 4+?|
|08-08-2011 10:25 AM|
|GoldenSahara00||I have had it too but I feel like its getting worse. I don't know how much should be there and how much shouldn't since I've only owned it a year of its life.|
|08-08-2011 12:14 AM|
|rmburwell||just want to put my two cents in, ive had this "problem" since i bout it, found that no matter what if you are parking your car, stop, put in nuetral, pull e brake, then put in park. havnt had the harsh feeling when putting into drive or reverse. i think its the strenous action of the transmission being left to hold everything insteas i have the brakes take the brute force of it all|
|08-08-2011 12:05 AM|
Jerry would it be possible that the tranmission mounts are just loose and they need to be tightened or repaired? I really don't know much about the mounting on a TJ but have been doing a reasearch and that could make sense with the jerking and movement I feel. The whole jeep lifts and lowers.
I will still check fluid nevertheless.
|08-07-2011 10:29 PM|
|GoldenSahara00||I'll check it out, I imagine if I need it flushed, do you suggest I just drop the pan, or do a full clean? I have heard alot of debates. if its low is it okay just to top it off with new as long as the old is okay? I can check it out in the morning.|
|08-07-2011 10:25 PM|
|Jerry Bransford||ATF level up to where it should be, checking it only per the instructions in your owner's manual? You don't check it with the engine off and cold, the engine must be warm and running and the transmission shifted through its gears and left in neutral before pulling the tranny's dipstick. The ATF should be clear red and not smell burnt.|
|08-07-2011 10:21 PM|
|GoldenSahara00||so playing around driving, it doesnt do it going from P straight into D in one fast motion. P into R, and N into R are the worst. N into D is iffy.|
|08-07-2011 04:47 PM|
|GoldenSahara00||I have to go to work, I am gona look at things again sometime this week, lots of stuff I need to look over. I will check out the cable a little better then but like I said it is snug, not loose or tight.|
|08-07-2011 04:42 PM|
|GoldenSahara00||As near as I can tell it is fine.|
|08-07-2011 04:32 PM|
|Jerry Bransford||P.S. The TC cable's length is adjusted at the engine end, where it passes through its mount just before it attaches to the throttle lever.|
|08-07-2011 04:21 PM|
|GoldenSahara00||Okay give me a second.|
|08-07-2011 04:19 PM|
|Jerry Bransford||The transmission has two cables going to it... one for the shifter, the other that heads towards the rear then loops back to the engine compartment is the TC cable which connects to the throttle body linkage. Check it at the end that connects to the throttle body linkage. It should be taut, no slack, but absolutely not so taut that it is pulling any on the throttle linkage.|

"I was looking for that cable you were talking about but wasnt sure exactly which one or how to tell if it was tooo tight, I took my best guess however."
I will as soon as I know what I am looking for.
|08-07-2011 04:15 PM|
Okay well tell me what to look for. I was thinking the cable that runs into a bracket by the drivers side near the front of the bellhousing. then runs up into engine, Was the only cable I saw that made sense but there are a few on passenger side I didnt look at. It felt snug. If I have to I can take it to my trans guy he is good but I would rather save money.

I have some freeplay in my rear Ujoints, I can push and pull and rock and it clunks and shifts somewhat. Pretty sure it is all Ujoint and not tailshaft at all... the rear ujoint seems fine but I will probably just replace them both. front feels okay but looks dry so I should probably grease it soon. I was looking for that cable you were talking about but wasnt sure exactly which one or how to tell if it was tooo tight, I took my best guess however.
I was also lookin for the speedo housing because I am gona attempt to switch that out if I can find a 26 tooth for a decent price...
