Yeah, the engine is getting peak RPM.
I just noticed by looking at the manual that the original MT2 was 1-gear only. However, I found that the 2-gear transmission is the same used today on the RS4 Evo, obviously with different gear ratios. The 1st gear actually do disengage from the shaft, 'cause when 2nd gear engages, the shaft will start spinning faster than the 1st gear (that is permanently attached to the double-gear pinion), so the one-way bearing will let the shaft spin free.
I'm now a little confused here, 'cause if we had a locked 1st gear, when the 2nd gear clutch actuator moves out, it would meet a faster moving gear body that would not spin at it's speed ('cause 1st was locked) and that would surely break something.
But I will suggest my friend to buy the rebuild kit.
Thanks KeithjV and nitro-rob
The first gear disengages because when second gear kicks in and grabs the shaft the one way bearing on first gear slips effectively releasing the first gear from the shaft. So does your second gear not engage then? You say you see the second gear engage and it appears the first gear disengages then say that you have a locked first gear which means it doesn't disengage. Can you clarify? Sorry for the questions and confusion, its hard to diagnose remotely. The second gear engages by centrifugal force that has a sort of 'pin' that engages the shaft and the timing of the engagement is controlled by the spring tension that is determined by a set screw.
I had a problem with my evo - the second gear hub that is connected to the shaft (and is engaged by the 'pin' that grabs the hub) came loose and when second gear was engaging it was spinning the hub that wasn't attached to the shaft. It would shift properly for a while when I tightened it but then stop shifting - in the end the solution was loctiting (is that a verb?) the set screw that connects the hub to the shaft.
