Hello, I have a 2000 WJ Select track 4.0L which seems to have a issue when making a left turn. When I make a left turn the auto tranny acts like it is slipping or down shifts down way to low and the RMP's wrap out before the tranny catches again. Almost like a nutral drop at times. Anyone have any suggestions on where to start looking? Is there an issue with the Select track "full time 4 wheel drive" when making a letf turn?

Thanks for any info or help.

The TC has no idea what direction you're turning, only that the front wheels want to spin faster then the rears...

Check the transmission fluid level. Park on level ground after the transmission has warmed up. Put the transmission in neutral and with the parking brake on verify the transmisison fluid level is between the two hot marks on the dip stick...

Why I asked about the transmission and turning with full time 4 wheel drive is becuase of the computer controll of the wheel slip. Since all wheels are in drive and yes one wheel turns les the the other while turning would there be a wheel speed sensor type kick down switch or something that would need to be replaced? I see where there is an issue with the cooler return filter replacement and possible simptoms there, but I really only have an issue when turning left? The fluid level is full and new. I did that first thing.

DELAYED ENGAGEMENT DUE TO COOLER RETURN FILTER REPLACEMENT (45RFE / 545RFE TRANS)

Date: 09/01/05

Model year(s): 1999-2004

Description: NOTE: This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales code DG4 or DGQ respectively). This bulletin involves a transmission delayed shift condition that may occur following the replacement of the internal cooler return filter.

Details: The customer may experience an initial delayed shift engagement following an extended off (not running) period of time, generally after being parked overnight. The initial shift engagement may feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine start.

The customer may not have experienced the delayed shift engagement until after the transmission has been serviced, where the cooler return filter was replaced during the service and/or repair.

The condition is not detrimental to the transmission but may cause concern with the customer.

The above condition may be caused by a suspect cooler return filter a part number of 04799662AB. This “AB” suffix / level filter may allow transmission fluid to drain back out of the torque converter. The drain back condition may occur over a period time when the engine (and transmission) are not running. With less fluid in the torque converter a delay in gear engagement may occur at engine start up while the torque converter fills to its proper fluid level.

All 04799662AB cooler return filters with the “AB” suffix are suspect. The above condition may be corrected by replacing a suspect “AB” filter with a new cooler return filter whose part number is 04799662 (with no suffix or with a suffix that is other than the “AB” level).

NOTE: The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part number is stenciled on the side of the filter case.

NOTE: A replacement 04799662 cooler return filter may come packaged with a separate threaded adapter stud. The threaded adapter stud is used to attach the cooler return filter to the transmission. Inspect the stud and note end without threads. Install the stud end without the threads into the cooler return filter and tighten the stud-to-filter connection to 18.6 Nm (165 in. lbs.). Once the threaded adapter stud has been installed to the cooler return filter, install the assembled cooler return filter to the transmission and tighten the filter to 14.1 Nm (125 in. lbs.)

i put a used 130K quadra trac into my V8 GCL replaced filters and fluid, had that slippage at start up and has gradually gone to intermittent slips to what feels like neutral and then reengage ,Now it is in that mode and only will grab when the engine is reved and jhas slippage and cannot be driven now . i replaced the throttle position sencor but no change, I was wondering if i was suppose to DRB scan tool to introduce the replaced differant trans??? at a lose man im pretty sure it is not the ab filter that i installed ,i did have to put that part in first before the filter. any clues

There is no computer control for the 4wd system...it is all mechanical. The only thing monitored is each wheel's speed which feeds into the ABS system for braking and also detects the speed of the vehicle. Neither of which should effect the transmission shifting.

Ok so why will I only have the trany slip when making a left turn and not a right turn? It isn't only when it is cold or first start up. It is all the time. It can happen when crawling along or gunning it? I have an old CJ with lockers and all the fun stuff which I did all the work. I am not new to Jeeps just this new Select track system on a auto trany. This is also my first round with Full Time 4 wheel drive. I thought the point of Full time 4 wheel drive would be to add power to the wheel that slips not just add braking to the other side? am I wrong on this?? Also since both wheel are not locked they will turn at a different rate right? That is why I was asking about making the left turn since it only slip then. Is there some sort of sensor which would adjust this? The filter change seemed like common sense, but I just bought the damn thing and had the trany serviced. It didn't start happening right away but is getting worse as time goes by. Other then adding a new filter again are there any sensors I should be looking at as well?

Thanks

I had exactly the same problem with my ZJ last summer. The problem only occurred after a left turn. It turned out to be the transmission control cable from the throttle body. It was out of adjustment (the transmission fluid was fine BTW). Once adjusted, the problem went away and hasn't returned in over 9 months.

I think what is happening is that like most 4X4's, it's usually the left front and the right rear that have most of the power when driving. If your model has the full time 4X4 quadra-trac then chances are that when you are turning a sharp left, it's the slip in the axle that is causing that hopping feeling or slipping. it's not a bad thing, it should be normal.
to test that theory, find some slippery grass or mud and try it in that condition. See if it happens. If it doesn't then it is due to the fact that the wheel is turning. On a non-slip surface like asphalt, the wheel has too much traction and is causing a hopping feeling.

My ram did the exact same thing. Only on left turns, and tripped a tranny code for a bad torque converter. And would kick out of overdrive randomly. Turned out it was low on fluid. Do a fluid and filter change, try some Lucas transmission fix.

I came across this thread last week when I had the same issue. My jeep is an 04 Jeep Grand Cherokee. I just finished replacing the transmission fluid and filter and it would downshift only on left hand turns. Turns out I was about 2 quarts low after the fluid change. I have the 42RE transmission and after a standard trans fluid/filter change takes 6 quarts.

Hey guys. I have developed the same problem on a 4.0L 2004 Grand Cherokee - automatic transmission. The engine briefly revs like it is in neutral when swinging a turn, then reengages suddenly. To me it feels exactly like clutch-slip on a manual - the engine disengaged from the transmission. My fluid level is good.

Reading through this thread, there seems to be two theories that fit:
1. That the filter has come loose in the transmission, allowing air to get sucked-in when the fluid moves to the side of the pan during a turn.
2. That the cable from the throttle body to the transmission control is adjusted wrong.... and somehow then messes up during a turn. I don't understand this one as much.. is the theory that this cable moves/swings during the turn causing the problem?

I vaguely recall that the transmission was serviced a few years ago, perhaps with an after-market filter. This leans me toward #1, but #2 might be easier to check.

Can some of you report back on what was the final fix?

Transmission slip

Does anyone have a solution for this transmission problem?

i put a used 130k trans in my V8 99 GCL replaced fluid and filters (pretty sure it was not the ab filter) but started w/the slippage at start up then graduated over a few months to slipping to what feels like neutral and re engaging right away or some time a few hours on the side of the road. the chk engine light goes on but when analyzed no codes come up. now i ve been towed home and the best it will do is a slippage in and out in drive when revved high and a little reverse the engine light stays on where it would shut of after previos events cant be driven now . I've replaced trans sensors (2) and the throttle pos. sensor w/no luck .The fluid level is perfect since install and perfect color. whats going on ? anyone go thru this ? or got a clue ?
