2005 Jeep Liberty CRD

I have a 2005 Jeep liberty CRD that I bought back in September. Starting the end of november first of december the jeep started stalling. When I first start it up I will put it in reverse to back out of a parking spot and everything is fine, when i go to put it into drive it will stall, Also sitting at intersections it will not stall but the rpms will drop fast and pop back up to where they need to be. Any advise on what may be causing this would be great. Thanks!

What is happening is the transmission drain-back problem. Changing the transmission fluid and BOTH filters may help this issue, as there is a weak flap inside one of the filters that allows the fluid to drain back to the pan while the engine is off. When you start it up, the transmission might be slow to engage, but in the swap from reverse to drive, the torque converter needs fluid pressure to unlock and switch gears, and without that pressure... When the transmission tries to switch gears while still engaged, it drags the engine into a stall.

Thanks for the advice! I just got the transmission fluids drained and the filters replaced. I will let you know if it fixes the problem...but so far so good! Thanks again.

I will be interested to know if your problem goes way because I am having the same problem and I am wondering if I should do the fluid/filter change or try flmans mod. (adding a check valve). I hope you are liking your CRD.

The flman mod might not be a bad idea either, if you are so inclined. I say this because the new filters could also be subject to the flap fatiguing, which eventually could lead the problem to return.

When changing the fluids - Be aware that it may take quite a bit more fluid than you think possible before the transmission is properly filled! My transmission change seemed done after 6.5 quarts, but while the gear engagement was solid (and VERY strong) right after the change, within a few miles it started feeling like it was wallowing and slipping from a standing start in gear (like from a stop sign or light) because the air was being worked from the lines. It actually took another 2 quarts (one of which I decided to use Lucas Transmission bear snot) and it has been running great ever since.

On a recent trip (Monday this week) at 75mph continuous for 375 miles, I booked an amazing 27.8 mpg

It is funny that this is such a common problem. Does anybody know if the back flow valve may have been upgraded in new filters?

geordi: thanks for the oil change tips and nice mpgs.

I had the same issue and had the fluid and filters changed at the dealer while addressing other issues. It didn't help a darn thing. Just living with it for now.

So it seemed to help for a time... but the problem is back once again. I guess I will try the next thing. Any more advice out there?

Try a bottle of Lucas transmission. That stuff is concentrated bear snot, and since I put that in my transmission, I have not had any problems until a couple weeks ago. I ended up doing an "impromptu" transmission fluid check and refill when the POS stock jack decided to depart it's duty station without proper authorization. The darn thing slid UNDER the transmission pan as the CRD fell off it, and it gouged a nice big dent in the pan... Wrecking the seal in the process.

Since a new pan is only $40 at the dealer (who I talked into shop rate of $28!) I said screw it and just replaced it.

Refilling with most of the recovered fluid (which was basically brand new fresh) and topping off... It did the same slow-to-engage nonsense while on level ground and warm several times to me. Bottle of lucas... Problem solved. Obviously there is a weakness in that check valve that the thickener in the Lucas resolves. Whatever, it works.
