Programming transmission WJ

Hi,

I have a jeep that many of you guys may never have heard of. Its a 99 WJ with a 3.1 turbo diesel from VM.
This car was produced for export only. Its identical to all other WJ's, except for transmission and engine.
I have a problem though, and was hoping for some input from you guys.

The lock-up only engages when passing 120km/t or about 75 - 80 mph. That is very high. All other jeeps with petrol engines have their lock-up engage at about 80km/t or 50mph. I suspect there might be a programming error from Jeep on all 3.1 WJ's. Somebody must have entered the wrong number or the wrong scale.
So my question is: Is it possible to reprogram when the lock-up should engage on ANY of the jeep automatic transmissions?

Hoping for answers!

Cheers!

Hi,
I'm in France, then, the 3.1 Turbo Diesel is known here.
On a french forum, one guy seems to have the same trouble, plus the first speed does not engages.
On his Gd Chee, the problem is maybe with the soleno´d, and the oil pressure sensor (not sure of the translation)

Hope you'll find some more information

Hi everybody!!
I have spoken with Jeep in Norway and they are aware of the problem. They made an inquiry about my question and directed it to the factory that built Jeep for Europe. The factory is located in Gratz in Austria. They wouldn't listen, and answered that the 3.1 TD with the 44RE transmission was programmed to engage the lock-up at 122 km per hour. Therefor ALL WJ 3.1 TD acts the same. They won't create new software even though jeep work shops from all over europe have asked these questions since the car was new in 1999.
I have created a group at facebook to try to get hold of enough people across europe or maybe the whole world. This might turn into a signature campaign. If we can get enough members, maybe the factory has to listen to us.

When the lock-up don't engage, the car uses about 0,1 to 0,2 desilitres more per 10km, it polutes much more, and the transmission gets warmer and wears more rapid. And when you ad the fact that Jeep probably have received hundreds, if not thousands og questions about why every jeep transmission engage the lock-up at 75 km/h BUT the 3.1 TD one can wonder why they haven't created a new software for this transmission. They did it with the 45RFE to turn it into the 5-45RFE transmission.

So if you own a 3.1TD join my group, and maybe we can persuade Jeep to help us with new software for this transmission.

Please promote this Facebook group in you own country. I have so limited knowledge of all the national and local jeep clubs.

No, it was produced "pre-exported" - in Austria, by Magna-Steyr, if I recall.

Apparently somebody used 75 mph when he *meant* to use 75 kph...

Like I said, Chrysler has always gotten 3rd pick of the engineers...

I stated EXCACTELY the same thing, but they wouldn't listen. The claim the transmission is produced this way, and that it works according to plan. Therfore, the transmission is not faulty and they will not look into it.
Most roads in europe don't even have speedlimits high enough to engage the lock-up.

I installed the "mystery switch" solution in 2012 and it has been a great upgrade to the 3.1TD.
All the engine noise problems because of high rpm's at higher speeds and acceleration are gone, and you really can use the engines low rpm torque instead.

Why are you necrobumping old threads about a vehicle that isn't discussed any more in this forum?

Why has someone posted questions regarding WJ in a ZJ forum?

Because it used to be all grand Cherokees not only ZJ so the old threads still pop up.
