what weight oil is in the 5 speed transmission?

Sorry, my info just states Mopar manual transmission lubricant.

I'd use BG's manual transmission fluid (it's not on the list below) or Pennzoil Synchromesh fluid Less expensive alternatives CERTIFIED to meet GM 9985648 and Chrysler MS-9224: AMSOIL Synthetic Synchromesh Transmission Fluid (MTF) Pennzoil Synchromesh Fluid Royal Purple Synchromax Capacity: 4.2 pints DRY is stated in the Owners Manual and the Service Manual. When performing a fluid change some of the old oil will not drain out. NOTE: 5W30 engine oil does not contain additives for use in manual transmissions. Additives in standard gear and axle lubes will etch the bronze synchronizers and 80W oil will not properly flow into the NV3500 bearings. WARNING:DO NOT USE REGULAR REGULAR GEAR & AXLE LUBRICANTS IN THIS TRANSMISSION THEY WILL DESTROY IT. Zee
