Mine used to do the same when I "backed" my trailer up my slanted driveway and usually just dropped into 4lo--no problemo-

Now I don't have to since my regearing-

I know this is an old thread; but, my Jeep now has the torque converter shudder when clutch is trying to lock up under 40 mph. I have an 2008 JK Rubi 4 door w/ auto trans and 109k miles. My mechanic suggested some Lube Locker "red" to help resolve the shudder. I'll try to remember to report back if that helped resolve shudder.

A problem like this might be corrected with a programming change. There is typically a pulsed signal to soften the engagement, and as stuff wears, it becomes more noticeable.

Fresh correct fluid might not hurt either, if it's old. In the old non-lockup days, none of this stuff was very critical, hydraulics just clunked the stuff in and out and the TC took up the slack. Such is the price of progress.

Occasionally I've had my jeep sort of search for a gear when I've had to stomp on it to avoid a situation in city traffic, seemed like it free reved and I let up on gas and then it shifted. Also sometimes it won't kick down until I practically floor it when driving up a hill at interstate speed. Going to get the fluid changed at next appointment 50K.

That may be a symptom of low ATF???

If you have cruise control set & the torque converter clutch is locked up, that can occur. I squeeze down on skinny pedal & turn off the cruise control & it kicks down to 3rd gear right away. Also, this helps avoid the 5K rpm kick down to 2nd gear.

That is my next step, if this magic fluid doesn't solve the problem.

Had ATF changed just 10K miles ago when I had the RubiCrawler installed and the transmission shifter position sensor replaced.

2008 jeep wrangler unlimited x 4 door 4x4
More problems then time... first car was a93jeep wrangle loved it wanted a newer one when they came out i currently have 88k miles now. .. at 35 the dealership had to rebiuld my motor lifters where tapping told the dealership on 4 occasions they where tapping didn't listen to me ended up taking them a month and a half... couldn't explain to me why they where tapping what caused it or that it wouldn't occur in another 35k mile lucky for me that hasn't happened. While in reverse or going up hills with any sort of incline my car will sudder/vibrate/shake only way i can think to discribe with our having every person on here drive my jeep. It is currently in the dealership because it for suck in 4x4 and the bushing on the channel which controls the linkage broke and my wonderful"sarcasm" jeep is now suck in 4 high and the dealership is starting my lifetime powertrain and motor doesn't cover it. So yes I'd say i have had lots of problems with my jeep

That said, I have no issues with the transmission under normal driving conditions (other than reverse).
That is a factory setting. it is not an issue and has a rev limiter in reverse.

I use red lubeguard and rarely now have the torque converter shutter. I have 116K miles on my 2008 Jeep and 3speed+ auto transmission is just great.

I'm not working for Robi; but, I understand that VegasRobi has 3.8 engines & trans combos taken out of Jeeps he upgrades to LS engines for pretty reasonable prices.

92,000 miles and counting. Change fluid every 10 to 15k or once a year without fail. I know the 42RLE gets a bad wrap but, its actually a very good tranny just the overdrive is a little tall for most user's who choose to run 33s and bigger hoping it stays locked in 4th even under heavy loads. The one engine it did suck balls behind though was the 4.0L that thing was just horrible. That inline engine was never meant for a big tranny behind it with overdrive. 32RH used in earlier 4.0s was the perfect tranny for wranglers. AW4 for the bigger Jeeps with a 4.0. Sometimes its possible to get a bad apple or two out of a lot but, thats with anything in this world. 90% of the problem is folks don't change the fluid like they should or use the wrong oil.

Soccer six in the mix.

Picked up my 2012 in late 2011 and now I've got just over 39,000 miles and no worries. Of course, I now regret saying this and have to find some wood to knock on.

W580 is a solid unit you should not have any problems especially if cared for. The engine will give you problems before the tranny does The 42RLE,32RH and AW4 are also very good transmissions. The AX-5 and 15 are junk as well as the NSG370 for a standard. Probably the best manual tranny would be the NV3550 if I remember correctly for the wranglers.
