Carrier gearshift binds in first gear

[Big D]

Gidday again,

I went ahead and shifted the oil filter and pulled the transmission top cover.

I've taken a series of photos of it from both underneath and on top taken through the top where the housing cap goes. Notice that on some of the photos the flash has given the impression of reddening of the areas affected by corrosion. In normal light, these don't seem as bad as the photos would have me believe.

However, looking at the corrision, there does seem to be some obvious very red rusty areas on the shifter rods as seen through the hole in the top cover. The corrosion on the underside of the shifter rods appears very dark and older although I am certainly no expert with this sort of stuff.

Overall, the corrosion appears no worse than that in the gearbox on my 1943 Willys. However at the same time this gearbox and engine was completely reconditioned around 2005 and the carrier would have only done 100 miles at the very most since then.

It looks to me like I'll have to pull all the shifter rods and clean them all up. I guess all this would only add to the binding when coming out of gear.

I would be keen to see what you experts think.

Thanks.

Cheers

Darryl
