RICK'S THOUGHTS ON TRANSMISSIONS & TRANSFER CASES

Rick started 4 wheeling in a CJ6 with:

• Aluminum case Muncie 4 speed from an early Corvette, model 18 transfer case and 5:38 gears
  
• Muncie 465, 4 speed with granny low, model 300 transfer case and 4:11 gears - this worked good for off road and street use

Then Rick moved to a NV4500 when it became available in 1993:

• 5 speed with granny low and overdrive
• He changed to 4:88 gears and kept running the model 300 transfer case
• This was a great combination for a manual transmission.
• Good for street, highway and off road.
• At 76:1 this is geared plenty low enough for rock crawling

Then Rick changed to a 700r4 Automatic Transmission for several reasons:

• It is easier to drive over technical sections when rock crawling
  
• Automatics are more forgiving -- the torque converter acts like a buffer between the engine and wheels
  
• Fewer parts break..
  
• Rick still runs 4:88 gears with the automatic and is happy.

About the same time he installed the 700r4, Rick changed to an Atlas Transfer Case

• This gave him a stronger output shaft (this had been a weak point in the drive train)
• Already having 4:88 gears, Rick chose the higher ratio Atlas (3.8:1)

Note: Advance Adapters and Teraflex will be introducing large output shaft kits for the Model 300 transfer cases. If you already have low gears, then this kit will give your Model 300 the extra strength it needs
