there are 104k miles on my car. are the gains worth it for a gen 5?

 

Go on Zzp and look under the trans section. Basically: input shaft, hardened 4th gear, shift kit, 7/8ths chain and gears, clutches, torque converter. You will want to have the valve body upgrades done as well. Dave at triple edge performance can build you a trans with these parts in it and ship you a whole trans as well.

 

At what point in my modding should I start upgrading my trans? Should I wait till I have bigger mods such as cam or intercooler? or just tackle it down before I mod any further?

 

That can break at any time.

 

You never know when its going to go but with it making more power than factory it could happen now but it could last years you never know. When I put the turbo on mine I was making about 300whp and my trams only lasted 7,000 miles after the turbo was installed. Then again they were a hard 7,000 miles lol

 

And my transmission broke, while I was stock

 

My tranny went out when I was stock as well. The transmissions are pretty big hit and miss. Hell my friend had the original in his 150,000 mile l67 and it lasted a long time with a turbo on 17psi.
I am a big fan of "Don't fix it if it ain't broke." Just make sure you buy a cheap decent one to have around to put in when yours finally does go.

 

well looks like I'm going to have to start doing some trans work as my next mod! I'll probably start by getting the shift kit or the gear ratio, if it's worth it? I'm pretty inexperienced with trans work so I apologize in advance for all the questions!

 

Those aren't going to make it any stronger. I wouldn't mess with either of them with the miles you have.

 

If ur gonna build the trans do it all or don't do anything IMO
