I have a 2004 LW300, 4 cyl, automatic transmission.
For history, a couple years ago the transmission started slipping. I had the transmission serviced and changed the fluid. That solved the problem at the time.
A couple of days ago it started to feel like it was slipping again. Then yesterday wile getting off a freeway, it just died. No forward gear at all. Reverse still worked. But none of the forward selections seemed to even be trying to move the car. No obvious leakage anywhere. No codes relating to the transmission.
Ant thoughts on what to try?

 

Andy is our resident L series guru. I'm sure he'll be able to help you. Being the novice that I am, it sounds to me like the transmission is shot and you need another one, BUT, I'm NOT a mechanic.

 

Does it try to move forward in manual low? It may have lost power to the transmission. I would start there.

 

For the record, what are the codes that don't relate to the transmission? PXXXX, Bxxxx, UXxxx.....

 

Does the indicator show the correct gear? Did we scan the TCM?

 

Hi & Thanks.
It does not even try to go forward but reverse works fine so it would seem power is getting to it.

 

I have one that lost first gear but backs up fine. I backed it out my driveway up a hill and coasted down in drive and when I got to an about 15 mph it shifted to second and took off. It might be a solenoid failure. I will pull a factory service manual and take a look.

 

The factory service manual automatic transmission book has 548 pages. Did you ever post codes? I really don’t have time.

 

Yes, please modify my request to a request for all codes.

 

The other codes relate to either the fuel tank EVAP system or my need to replace the catalytic converter.
Note that I've replaced both O2 sensors with new ones and the codes remain, so they probably relate to the cat.
P0455, 0442, 0446, 0496 - Leak in Evap
P1137 1138, 0137 - O2 sensor 2
P0131- O2 sensor 1
P1171 - Lean fuel on acceleration
P0420 - Catalyst efficiency low
