Tranny shifting issues...

psinsyd · **Posted:** Mon Jul 03, 2006 10:31 am

Hey everyone,

Just curious if anyone else has experienced this. On my '02 Renny w/ 59k miles on it, it's begun taking about 3 or so seconds to engage in drive after shifting into drive. This is after it has been sitting for a matter of hours. Sometimes it even slightly clunks when it finally engages!

Another symptom is that the shifts don't seem to be as smooth as they should be. They're somewhat jerky as of late.

I've already had the fluid level verified after the pan was dropped and the filters changed in it. I also made sure to use ATF+4.

Does the Liberty come with a 7/70 powertrain warranty, and will this be covered? I also purchased the 8/80 extended warranty where the most I have to shell out for service is a $100 deductible.

Thanks as always to everyone in here for the help!!!

In the new CRD's and other DC rigs with the 5 speed this was a symptom of a bad filter with a faulty valve that let the tranny fluid drain from the tourque converter. If it wasn't repaired under the TSB then the TC sometimes failed. If this started happening after the filter change then you may have a similar problem.

Yep, sure enough. Checked on alldata.com and there is a specific TSB for that exact condition, "delayed engagement after filter R&R". TSB number is 21-015-05. Thanks man, you're awesome.

I'm expecting this to be covered under warranty, right?

Thanks again!

Did Jeep service it with the new filter you talked about or someone else? If someone else did then you might be into finger pointing. If jeep did the work I would say it should be warranty with no deductible since it could be considered warranty on the filter job.

Get it done fast whatever you do as it will cause significant damage if you don't. In the meantime let it warm up a while in N before you shift into gear. That will help.

If it's too late, talk to APS. Get a built torque converter from them and send them your core. Get the performance shift kit for it from them, and have the valve body rebuilt. Their torque converter for the 45RFE only looses 12% compared to the stock 20%. In mine, the multiplier has been increased from 1.93 to 2.53, and the stall raised to 2500 rpm. Send your ECU to B&G Chrysler, and have them flash it with a high performance tune with the torque management deleted. You will be very happy with the results of this combo.

im taking our liberty to the stealership tomorrow for this very same problem.
its an 05 with 22k on it. even after i let it warm up, it still takes a few seconds to shift into drive. i have revved the engine up a little to get it in gear, but most of the time it doesnt work until it wants to.

ill follow up with what the stealership says.

Sounds great, keep us posted! I've got an appt for Thursday, first thing in the morning. I also won't be driving it on Wednesday. I'll keep everyone here posted too.

Thanks everyone for the heads-ups!!

Get 4.10 gears, aem cold air intake, flowmaster exhaust, and you should be running low 14's

add a 50 shot of nitrous and you should be into the high 13's.

just don't make any sudden turns.

My 05' does this when I back ouf of my driveway. When I go from reverse to drive it takes along time to shift and when it does it shifts hard even with my foot of the break.

I think it's prety normal for the 42RLE though.

Edit: My driveway runs down hill so that may have something to do with it.

Yeah, and how much $$$ does that run???

Just a quick update. Dropped the KJ off at the stealership today and gave them the TSB number while I was at it. My appointment's not until tomorrow, but I wanted them to be able to shift it after it's sat overnight.

I'll keep everyone posted.

I spoke with a good friend who is a mechanic at a jeep/dodge/chrysler dealership. He told me that it is common to sometimes have a slight delay when shifting because the 42rle uses electronic solenoids to create the pressure to shift into drive. Most other transmissions use pressure from the pump, typically faster response. If you listen to you tranny when you shift you should hear the solenoid for about a half second. If it doesn't start building pressure within a half second or takes a few seconds then you might have an issue. I noticed the delay sometimes, especially when you back out of a parking space. It has improved since I changed the filter and fluid myself.

just got the libby back this afternoon. sure enough, they did have a tsb for the mis shifting tranny, but it wasnt the one that was quoted in an earlier thread above. they did flash the transmission and it fixed it. they also replaced the fan / motor and recharged the ac. engine light came on in route to the stealership. so they reflashed the ecm now all seems well in libby land.

if anyone's tranny is shifting like this thread has described, take it to the jeep house and have them fix it. the tranny is absolutely not supposed to have a delay once you put the stick in drive, or any gear for that matter.

Hey everyone,

Picked up my libby today from the stealership too, and sure enough, it sounds like the return filter was the issue, allowing fluid to drain back down from the tc. So essentially, they had to do the tranny service over again.

I have the 42RFE trans (I think that's the model. I haven't checked the sticker on it since I did the trans service).

Thanks again everyone for the input regarding this!

For the 45RFE/5-45RFE, it's about $500 for the converter, and around $100 for the performance shift kit. About $1000-$1200 with all the labor included. 4.10 gears help too. The rear gears with a rebuild kit will be around $300, and a front diff out of a 4 cyl will probably get you for around $600, if you can find one. You'll be looking at around $600 in labor to do the 2 diffs. The pcm upgrade is around $450. So around $3000 for the complete upgrade. Of course this is assuming that you've already done the obvious of upgrading the exhaust, intake, and have done something to get some more air to it.

Dealerships love this kinda stuff, you know when you go to trade in your riced up vehicle and you're trying to convince them how much more your vehicle is worth because of all the extra money you dumped into it. Then you have some manager (like I was) come out there and bust your balls because no one will give you anywhere near the money you expect for your trade, all the while you really haven't improved your vehicle in any substatial way no matter how much money you wasted on it.
