First Winter Project: Transmission

Here are some pictures from the recent project I’ve started:

First step – On the bench with the tail housing (Center differential housing) off and draining.

Once I got the case open, Inspection suggested that a broken 5th gear was the cause of this “noisy” transmission I got for free as a donor case. Not sure how it was driven at all like this but good thing I have an extra.

With the gear stacks removed, I laid out the old “donor” parts on the right with the new JDM parts on the left. Going to have to some mix/match to make sure the bearings and gear ratios are what I want. Overall I’ll be upgrading the front differential (just to the left of the case halves) from an Open differential to a helical LSD differential. I’ll use the pinion shaft out of the JDM transmission to move the final drive from 4.11 to 4.44 to get better acceleration on the track.

More to come. Let me know what you think.
