I just bought a 1998 Jeep Wrangler with low miles and recently it started to make some noise under the vehicle. I thought it could be the exhaust pipe just vibrating, but when I tried to take out the skid plate to see what was the problem, the transmission was actually resting on the skid plate. I'm pretty sure it's not supposed to be resting on the skid plate. Does anyone have an idea where the noise could be coming from or if the transmission is really supposed to be resting on the skid plate? Thanks
