Title: New/Rebuilt Muncie transmission break in
Post by: JGraft on January 09, 2023, 06:10:59 PM

Hello CRG experts,

I recently purchased a rebuilt Muncie 4 speed transmission and are reaching out to find out if there is any expert guidance on the break in process for it. Obviously the first step is to fill the transmission to the correct level with recommended lubricant.

1. Should the transmission be started in neutral and allowed to run for some period of time before trying to shift into any of the gears?

2. Is there an order of gear engagement (including reverse) which should be followed as part of the break in process?

3. When should the initial break in lubricant be changed out?

Thx,
Jeff

Make sure you don’t use a synthetic lubricant. I think lube also needs to be a GL5
