AKA MQ500
AKA the meanest transverse gearbox available so far
500nm input torque rating, coaxial slave cylinder, 1.125" 26 spline input shaft, 6spd, 190 lbs dry
They're in the TT-RS, the tiguan, seat alhambra, audi Q3, and transporter vans from what I've seen.
I've got one of them, code LMU, through the free ETKA I've found the 1,2,4-6 ratios, but nothing on the final drives or third gear. If they're the same finals as the gasoline tiguans in the US, the overall ratios on this trans are deeper in first gear and taller in 6th than the EBJ/EGR 02J's first and fifth.
The only ones in the US with the transfer case output are in the TT-RS with tall final drives and very deep change gears.
Their transfer case box outer casing will interchange with similar application automatic and DSG transfer boxes, but the splined shafts are different.
I've got the automatic transfer box and it does bolt up nicely, but the spline interface with the differential carrier is larger diameter and finer spline on the automatic, no contact is made.
The stub axle for the RF drive axle stub that passes through the transfer box is also smaller in diameter so it does not engage the front differential. The outer spline on the transfer box that the RF inner CV fits onto is the same spline as the LF output.
If you do import one, make sure to get a transfer box as well, they're uncommon over here.
The transfer box gears are 17 and 27 teeth, with the 17 tooth one going to the rear drive, propeller shaft goes 1.5663 times wheel speed. Not a common rear differential ratio at all from all my googling. I've got the rear differential from a toyota matrix, 2.27 ratio and the overdrive unit from a 42RE, ratio .69, makes for something close enough to live with through different tires.
The input shaft spline is the same as a lot of GM and Ford applications, but they're all 10" plus clutch discs, and I'm looking for some 9" ones. They'll come across me eventually.
ETA: got a 7.25" quartermaster clutch coming, took a lot of figuring but it may well turn out what nascar folk call 1 5/32" might be what everyone else calls 1 1/8", if not then I'm out another $120. To be put into a 30lb or so pot flywheel. Have to figure out if the starter ring gear's similar to the other transverse 4cyl ones...
The bellhousing has no hole for the timing marks to be accessed.
Bell bolt pattern is the same as all watercooled 4cyl. Some have been adapted to VR6 motors.
They take a 240mm clutch, DMF of course.
So, anyone else have info on them? Ratios especially!
