Why does everyone bash the 6spd tranny

From what I know the reason why the 6 speeds have proven to be weaker is because the gears are thinner than the 5 speed. I have friend who has a IX mr and is about to buy his 4th 6 speed trans. Yes he drives like an idiot and bashes on his car, but hes only putting down 350hp/tq. The 6 speeds however can be beefed up to handle more power and the reason why people should still consider them is because of their ease of daily driving and more specific gear ratios for track use.

The whole reason why I asked was because I used to have an 03 with the shep 5spd and now im looking at an 05 mr and im iffy about the 6spd

Spot on, has been mentioned a few times but throwing 500 ft/lbs of torque at any tranny and expecting no issues is a bit....unrealistic. If you go for the 6 just take a bit more caution as power goes up, either way just make sure to keep up on fluid changes and dont drive it like you stole it!

I prefer the type of tarmac that turns instead of being straight, so that probably is a factor. I've only launched it a few times, and I'm still on the stock clutch.
What power levels are you aiming to achieve and type of driving? Sometime in the not so distant future I'll be at ~550whp
and I'm not going to change to a 5 speed. I say it really depends on if the driver knows what they are doing. That and if you have a clutch that is overkill.I mainly want the shep gearset because of the 4.09 final drive.

The reason the 6 speed are "weaker" is because of two things.
-They have a thinner 4th gear that is prone to failure
-Next, since there is more gears crammed into basically the same area, the 6speed has less fluid capacity.
Most of the 6speed failures happen on road course. What happens is the little amount of fluid gets too hot and the thin 4th gear fails. In theory a transmission oil cooler would fix this problem, but most just go the the 5speed instead.
I like the 6speed (even though never owned one). Its much smoother then the clunky 5speed and is way better for daily driving IMO.

I'd say go with it. I'm at 400wtq and a little over 400whp and haven't had any issues whatsoever. It's my DD and I like to make her scream, so she does get action.
