I've searched and could use a bit more opinions so please don't bash this thread!


Should I swap to a 5 speed? Or should I pull my 6 speed and send that to get built? Really like the 6 speed and don't wanna take away from that but don't want it in pieces either..

I appreciate any opinions in advance and other 6 speed owners' thought about this!


Thanks!

 

Has a lot to do with the driver man. How many miles on your 6 speed? Are you the original owner? Do you jam it into gear at high RPM? Grind gears? Good condition 6 speeds with good drivers should be fine at 450 whp. All transmissions will eventually turn to **** with a bad driver, even if the car is stock.

 

Currently only 30k on car/trans. Has not been beaten on by me since I needed a clutch for a some time so no jamming into gear at high rpm. Gears do not grind but 1-2 and 2-3 are a bit notchy but i think that may be normal. Its babied.. Recently had the clutch done and just finished the break-in period on it so before I throw some parts down, just looking at the long run..

If it is to remain a street car the 6 speed is fine even at 500whp level. Where people start to run into problems is hot lapping the car in 4th gear.

 

Yeh street car. Only pulls, won't be doing any launches. Would a "trans cooler" help?

 

Shep Ultimate Ratio 5-spd. /thread.

The ratio's are perfect and far better than the stock 5-spd while not having the fragility of the 6-spd. I've run all three transmissions with various power levels and the ultimate ratio is head and shoulders over the other options.

 

I have 355awhp and 335tq and my 6 speed started grinding. I just do hwy pulls like you and 3rd started grinding. Still went in fine and never locked me out for over a year but just go to the point where it was very annoying so i bought a built 5 speed. I do miss the smoothness of the 6 speed but i do like no grinds and less shifting. I would say save money for a swap but dont do it until you start grinding or really have to.

 

380/360 on E85 w/ stock turbo.
Dont really go above redline,
shift at about 5 grand usually.
I recommend only make hard pulls in
3rd or 4th.
No issues.
Take care of her
and she'll take care of you.

 

i used to race my car at the strip regularly.... ran a 12.0 on street tires with my 6spd... developed and ran a short throw shifter that made it 2.5in throw down from 4. i routinely put the car up to 160mph on the 60 mile drive to my daughters house. ON DESOLATE DESERT ROADS... even made runs over the two 7 and 10 mile mountain passes we have in the area at speed over 120... and 150 when i was running against my friends bikes. if i had to put a number on it i would say 150 passes at the track, 100-125 passes at 150+, and easily 50 passes over the mountains at speeds over 120...

all that beating... and all the abuse a short throw can put on the system... and my 41k miles on my 6spd never did it a bit of harm.

all the hype about the 6spd being a glass box in my opinion is failures due to abuse and not it being weak in itself... i wont say it will hold up to 600tq... show me a transmission that can happily without an issue... but i will bet if you treat it right, use the right fluids, and drive like you should then it will be fine at reasonable power levels...

 

Hmm interesting.. I would rather pull my 6speed before it blows so I can at least sell it

 

i will pay 300 shipped... i mean its a glass box afterall and cant support any kind of power right?

 

/\/\/\ seconded but I'll go $301

LOL

 

^^ Not that desperate
