A few words of advice from
www.ecotecforum.com/forums/showthread.php?9897-How-to-install-LSD:
"...with an F35, installing a diff in that is a bit more involved than installing the Team Green in an F23. There are special tools needed and youll need a new nut and crush sleeve for 5th gear, differential bearings as well as the gasket for the side cover, all these things are GM/Saab parts only and will run you around $200 in parts."
It wouldnt let me see any of the thread on that form, I will freely admit Im stupid when it comes to the internals of a transmission.
I know nothing about taking one apart, rebuilding it and putting it back together. I have never even read over the instructions for doing it. I can however take a GE a Pratt Whitney or a Rolls Royce jet engine apart and rebuild them. Its all in what you are good at and what you know you are good at. I havent tried doing a transmission, but thats not to say I wont try it one day. Im up for a challenge sometimes.. I read that the special tools that you need to take them apart are right around $100.00 which isnt bad for something you could be using often until you do things right...lol
I did find a few places where you can buy them rebuilt with the LSD installed and the performance upgrade already done for the SC or TC conversion to the cars. Prices weren't to bad, I have paid more for a transmission a couple times in my life. They were all between $1795.00 and you could go all the way to almost $4,000 for one. Depends on how much hp and torque you are gonna throw at it. If you need it to survive being hooked up to 300hp or 600hp you have to dig into that stack to make sure it does. The more HP you produce takes more money to make and that means it takes more money to actually put it on the road...lol
I found a 2007 Cobalt LS 2.2L with a 5 speed with only 67k on it a little while ago. Clean clear title one owner car and he said he would pull a carfax on it when I get there to look at it. Im not going any where today with this back screwed up, but Im hoping I can get out tomorrow. Asking price on the car is $2800 which really isnt to bad makes me think he only wants $2200 so he bumped it up to have room to haggle. I know we have some 2.4 and 2.2 cars in this area for $500.00 and up. A bunch between $500 and $2,000, I have been ignoring them for a couple months now...
