Hi All,
Wondering if anyone has a similar issue or suggestions.
I have a 2020 JLUR Diesel with the 8 speed auto.
When going down a steep brumby trail section . RPM will go from 1000 to 2000 without me touching the gas.
Usually I am going slow just letting the engine coast. Speed is constant. Then RPM will jump. Sometimes it will come back
down and go up again. Sometimes I have to tap the break or gas pedal and the RPM will then go back down.
On one steep trail it was in 2nd. RPM = 1000, Speed and RPM was constant... or just slightly increasing. Then it jump to 3000 RPM.
A bit scary when a few feet to the right is..... a cliff.
Starting to do the dance with two dealers.
One of them said there was a speed sensor error code. They updated the power train software saying it was a bit old.
They said if it happened again bring it back and they would replace the "valve body".
It happened again so I took it back. They said there was no code this time so they could not replace anything.
It has done it in 2wd on pavement. Its not that often.
Off-road bump down hill sections it will do it a lot. I have had it increase RPM 10 times in one day.
Any ideas?
