Check This MR Trans Out, Never seen one like this before...

Sorry for my stupidity and off topicness but what is the benefit of MR gears, and MR gears are only in 6speeds right? Again, I really know nothing tranny wise about these cars.

[x2percentmilk]

MR 6 speed gears were slightly shorter, theres a graph floating around somewhere that shows all of the gear ratios.

'MR' is a misnomer, as far as we know all JDM 6 speeds had different ring & pinion gears within the tranny and used a 5spd rear end. So fittingly we call them 'JDM' gears, not 'MR' gears.

I'm not aware of any difference between USDM & JDM 5 speed gearing though. Did Mitsu even make a 1st gen GTO MR?

Here's an online caps, I posted it before, it probably could use a sticky-ing:

I think either the plate or CAPS has an error. CAPS number is MR111883.

The plate should have an error. Mitsu part numbers are usually 2 letters and 6 numbers. Should be a 25 spline output shaft.

Probably doesn't make any difference but some odd things in the pictures could be due to the possibility that it may have come out of a "Right Hand Drive" vehicle. Just a thought.

Yeah MR is the Mitsu part number prefix, NOT from an MR edition GTO.

The only interesting thing about that trans is the piece attached to the shift linkage. Haven't seen that on a 5sp before.

[Austin@STM]

^ you mean the counter weight?

I've seen a few like that. I haven't seen any counter weights on 5 speeds that go straight out. Most of them face down on a 90 degree angle.

Part number MR111883 is a replacement for part #: MB936206. Between these 2 part numbers it covers all TT version of the 5 speeds. Nothing special about it from what I can tell. However ASA/CAPS doesn't tell you anything about the gearing. However if it's a replacement for the standard gearbox then we have to assume it's the same gearing.
