From what I understand, a rebuild on a M engined Jimny auto is......don't bother, buy a new box from Suzuki or find a known working box from a wrecker.
There are no aftermarket parts, everything is (relatively) expensive from Suzuki & lots of it needs replacing = uneconomic.
Rough cost of a new box (a while ago) was circa $6k.

A quote is "At 110km/h both variants" (means auto & manual) "will sit around 3250rpm......" - this can only be if the diff ratio in the auto is indeed lower (numerically higher number) than the manual, to compensate for the 'overdrive' gearing of the auto top gear, compared to the 1:1 ratio of 5th in the manual.

The ratios must be as Suzuki quote them for the new Jimny - unless the manual is not 1:1 for 5th gear.
The tyre size is the same.
The auto, with overdrive 4th at 0.697:1 would be at lower revs with 4.09:1 diffs
The manual, with 1:1 5th would rev higher with a lower gearset like 4.3:1
If the gearing is auto = 4.09 / manual = 4.3 - they could not both end up doing approx. the same RPM (3,000ish) at 100km/h.

Most people here are forgetting about transfer case. On the old Jim, 1:1 high for manual, 1.3:1 high for the auto.

So for the old (international) jim you get:
Auto: 0.696:1 X 1.32:1 X 4.09:1
Manual: 1:1 X 1:1 X 4.3

So according to that the manual should rev higher and thats basically what I see.

The new jimny I am not aware of what the gearing is, but what I can say is the 195/80 tires are taller ans thinner than the previous 205/70's


EDIT:

Found some information. Looks like they have the same transmissions (at least ratios) and have switched diff ratios from auto to manual. Explains the early recall...

https://www.globalsuzuki.com/automobile ... index.html

So now the manual should rev slightly lower than the old model and the auto slightly higher. With a little more power and lower gearing the auto must feel quite zippy. Still should be a 6 speed :)

Yeah, new Jimny diff ratios are different to what ZUZUKI quotes. Manual is 1:1 5th and 4.09 diffs, Auto is 0.697 4th and 4.3 diffs.

No mention at all of transfer case ratios.

The global site has the transfer listed. Same as the last model. Interesting they have changed the diff ratios around.
