Opinions: Are A340 Shift Solenoids A Service Item?
Saw another post on the board about a sticking shift solenoid in an A340 auto trans.
I have an '89 3.0 auto with 134k miles on the trans.
As often as I see these posts, the thought has occured to me that the solenoids are almost a service item. Any thoughts on that? Also, what mileage would one target to swap them out? 150k?
When I get into a really remote area the one thing that nags at me is that thought of losing a shift solenoid in the middle of nowhere and having to deal with that on the way out.
Thanks,
Mike

If there is an electrical problem with the solenoids, you'll get a flashing code with the OD light. If there is a mechanical problem there will be no codes. There are no replaceable parts on the solenoids. You can pull them out and check them.
The shift solenoids work as a pair.
1st gear-no.1 on, no.2 off
2nd gear-no.1 on, no.2 on
3rd gear-no.1 off, no.2 on
OD- no.1 off, no.2 off
