The tranny itself is a weak point but I'm about to embark on it's inner workings, i'm buying a 95 2wd 360/auto bad trans to rebuild and keep motor for a spare. The PCM's should interchange right? Anyway the trans will go on my bench and we will get aquianted.
Sadly, a 318 isn't a 350 or 351. While it's a great motor for longevity and general driving and transportation, using one for what you'd like is really stretching it's capabilities.
I checked my owners manual, and it tells me a 318 ext cab 4by will pull a 7200 lb trailer. It also says my truck will do that, and it will, but not very well. Through the panhandle of Texas, yes. From Phoenix to Flagstaff, or Flag to Albuquerque, not so well. But I also have a lift and bigger tires with 3:55s.
About a month ago I pulled a flatbed 2 axle U-haul with two ricks of wood about 70 miles. Had to leave the overdrive off and got about 10 mpg through the hill country here. OD was a waste and starting from a dead stop was a nightmare.
I've had several old school 318 trucks and vans, and while they were great for hauling kids, dogs, lumber etc, I couldn't tow my '74 roadrunner with a dual axle trailer.
I wish you the best with this. Mopar to ya!
