Absolutely NOT!
You should go to a real mechanic. JL lacks the expertise for this and Firestone is nothing but a bunch of bead-busters. Find an independently owned and operated shop with a good reputation.
It’s not losing coolant or oil just checked for any leaks but I am worried cause no my car will only go to 3k rpm before I change a gear then goes back down to 2k
Two quarts of oil every 100 miles is a disaster. I wouldn’t trust this car for a 10 mile trip.
“only go to 3k rpm before I change a gear then goes back down to 2k”
that could be normal, if you are only applying gentle pressure on the throttle (accelerator). The transmission computer downshifts under that condition. What we were reading was that you could not get the engine to go over 3k even in neutral.
@SpacelessMoney I think the only course for you is to spend about 100.00 to 150.00 and have a shop determine just exactly what this vehicle needs. You say you are using oil and had to add coolant then say you have no leaks.
There are several of us that just don’t think you should make your trip in this vehicle. A rental is recommended.
