My 06 Liberty has a trans issue. When I am coming to a stop but dont come to a full stop and then accellrate the trans will flare then hit/slame into low. The engine idles a little bit low also(all the time), I've been trying to hold the revs up a little to see if this would correct it(thinking that its just low thottle pressure). Anyway, is the throttle pressure adjustable on this trans and also can the idle be turned up without a hassel. I checked the trans fluid level in N when it was warm...... also forgot to mention that the trans only does this warm. I bought this veh a couple of months back but didnt see this issue before.... I dont think it was there Thanks

Raf..
Talked to Scott
He said that tranny has 3 speed sensors, one of them might be bad...does it turn on the check engine light??

Jeep uses 2 differnet trans in those if it is the 45rfe they had some problems with the seal in the pump where the filter goes in they would leak and you would get air pockets they also had a run of bad cooler line filters also that would cause engagment problems.Both filters are in the pan the other trans is a 42rle it has only 1 filter and I have seen a few with problems with the o-ring on the filter.

Dusturbd, from what I read, the 42rle has the trans cooler in front of the rad and the 45 does not. Is there anything else that I can see that tells me which trans is which thanks

Very simple.... 42RLE is Gas engine 45RFE is Diesel engine There are 2 variants of the 42RLE in `06 depending on which way it was ordered...One with Variable line pressure and one without Quote:
Talked to Scott
He said that tranny has 3 speed sensors
Find someone else to talk to...BOTH the RFE and RLE have only TWO (input and output) speed sensors.
Raff...to answer a couple of your questions...NO you can`t change the line pressure, NO you can`t change the idle speed
Has this had the fluid changed lately ?

I dont think so.... I bought this 06 used a couple
of months ago but havent driven it much(I was out
west with my other ride,wife's truck)I did see that
you should use 1 type of fluid only otherwise it
could/can have issues. Since you say the idle and
trans are a fixed condition(cant be changed) how
do I get the idle up a couple hundred revs.. is this
all in the computer, if so, do I get it re-flashed
and the same with the trans. This is under warrenty
but I would prefer to correct it before it really
be comes a major problem
thanks

So, I have the non-VLP unit.... is there something that can can be checked to correct this flair condition coming to a stop. If I do come to a complete stop and sit for a moment it will be in low and its fine. I was just thinking it was a line pressure thing but I could/most likely be wrong. Or should I just take it back to the dealer

Is this thing on ???
Since my opinion dosen`t seem to count, i`ll throw this last thing out.
Raff
Since you are unsure of the trans history, a couple of things...Has the battery been dead or disconnected lately? as this will clear the learned CVI values
At a minimum, the first thing you need to do is get somebody to do a Quicklearn on it, this will reset the clutch volume indexes (CVI), if you do, have them record the before and after, On the off chance there is an internal issue this will help in diagnosis
As I said before, you can not change the idle speed, it is dictated by the PCM and even if you manage to physically open the throttle blades it will then set a "target idle not reached" DTC

Rick, no the battery hasnt beedn disconnected or
dead. What is the idle speed for these, mineis
(on the tack) 475-500 in gear. If I let off of the
brakes on a level road at idle it doesnt move forward
at all, to me this is a touch to low(idle) which
made me think of line pressure on the trans issue.
Also what is this Quicklearn thing(no clue here),
is this a DRB thing
