Transmission Fluid

Bruce,

I think the only reliable way to check transmission fluid level on an LXi is by using the Allison keypad. Simultaneously depress the up and down arrows for 5s or so. If there are any logged diagnostic codes they should be displayed, after that the transmission will display the oil level. If the transmission isn't warm enough it will tell you. If the input shaft is spinning too fast it will tell you this too. Once warn and once input shaft speed is okay you'll get a fluid level read out. It will say something like: "OL: OK" if everything is fine; if low 1 quart it'll say something like: "LO: 1", etc. If you're doing this at a campsite you can warm up the transmission by applying the brake and putting the tranny in gear. You can even bring the revs up a bit to speed up the warm up time.
