I have had my TJ for two weeks,but couldn't drive it until last night because I was waiting for the previous owner to get the title in the mail,so we could transfer it. Now it's mine, & I have already noticed a few problems. It has an exhaust leak & sounds like crap. I think either the manifold is cracked, or it might be leaking at the manifold flange. I laid underneath it, & what I can see of the exhaust looks good, but I can't see up to the manifold. I have to get it up on a lift so I can see everything. Are the 2.5L manifolds known for cracking?
The other problem is the trans (3 spd auto) when coming to a stop, it shakes & shudders like it is going to stall.When pulling out,the engine RPM will raise up for a second, then it will clunk like it is dropping into gear,then it will finally move forward.When putting it into reverse,nothing will happen for a few seconds,then it will clunk & go into reverse. I plan to take it to a local trans shop to have the trans serviced & have all of the driveline fluids changed. Are they going to tell me I need a new trans, or is there another part that usually goes bad causing this shifting problem?
