I have a 2002 4.0 automatic with roughly 111,000 miles. What 5 speed manuals will fit. I would rather a 6 speed so any info will be greatly appreciated.

 

2001-2011 Ranger or Mazda B4000 M5OD-R1HD(M5R1HD) 5-speed, matching your drive train, i.e. 2WD or 4x4

No 6-speeds unless you do a custom bellhousing

Its actually easier and better to sell the auto Ranger and buy a factory Ranger with manual trans

Things you also need
Drive shaft from matching length Ranger, i.e. regular cab or extended cab or long bed, if 2WD, 4x4 wouldn't need this
Clutch/brake pedal assembly
Floor plate and boot for shifter
Your computer reprogrammed to remove auto trans software, or 2002 computer from Manual trans 4.0l WITH its PATS keys
You can run the vehicle with computer as is it will just have CEL on full time and idle high

I have been told you can remove automatics column shifter from steering column, and install blackout plate to cover up the P R N D 2 1 below cluster

 

yeah with that amount of modding it would make more sense to sell and buy a stock manual trans truck. But if the OP wants to move forward with this craziness, may as well get the 5.0 bolted to the front of that 5 speed transmission
