Hello

What all does it take to adapt my 2000 gmc trucks 5 speed trans to a 5.3 or 6.0 engine.

Nothing, just take your motor out and drop the new one in. Nothing special required at all.

 

Do any of yall 5 speeders have a problem with the 2-3 shift or know of anythign failing causing it to hate the 2-3 shift? My buddies Regency usually will not make the 2-3 shift under high RPMs.

 

Barras. I just recently started having problems during the 2-3 shift. I wound up blowing my throw out bearing monday night doin a 2-3 at high rpm.

 

thanks for the info. That is what i was hopping for. yea i sometimes have a problem with my 2-3 shift at higher rpms. i would like a t56 but it is out of my price range at the moment.

 

There is obvioulsy a problem with the design of the internal shifting rails. I and my friend have had problems with this.

 

how long do you think my transmission will last behind a 6.0 with cam and headers

 

The 2-3 shift is a b*tch. Mine has 2700 miles on it and from the sound of it, it looks like it will always have that hard shift. I thought because mine was new it was so tight it would not go. Has anyone seen an improvement with an aftermarket shifter like a hurst or something?

 

I had a problem with my 5 speed the next day after I bought it. It would just pop out of first gear at the light. It would do it on a hill, and I would almost hit the car behind me. I took out the 5 speed asap, and put the 6 speed in. That was one of the best things I did to the truck, other than the turbo. mjhoward made good power with the 5 speed, 400 plus to the wheels, ran 12's with it. A stock 6.0 will not put out those numbers, if he can do it, maybe you can. I am getting lucky on my stock 6speed. I thought it wouldn't take the weight of the truck, hell it's taking the weight and 600 plus HP almost 700tq to the wheels. No signs of breaking yet. sometimes you just get lucky.... Good luck!

 

I have a Hurst shifter . 1st. to 2nd. is better but 2nd. to 3rd. is still a bitch. I agree with MJhoward , I think it is in the design of the trans.
