When to turn overdrive off?
I'm wondering about when to turn overdrive off, I have a few questions:
1. I read the general rule of thumb is to keep it on when cruising above 50mph (highway driving) and to turn it off when stopping and going under 50mph, or when towing. Is this a good rule? The site I read it on was not jeep specific.
2. Is my understanding correct, that "overdrive" refers to the 5th gear and by turning overdrive off you will only be able to shift between gears 1-4?
3. This is a little off topic, but how would a superchips flashpaq work with overdrive? Any problems?
I've always kept it on, except last week I turned it off on the highway and drive aggressively, it was a lot of fun but my average RPM's increased by about 1500 so I'm assuming it was bad for the engine (and unsafe).
Thanks! And sorry for so many questions, any help would be appreciated. I want to take her to at least 300K!
