Gentlemen:
I am fairly new to the 3800 scene, but I am a HD Diesel mechanic with quite a bit of experience and I am ready to start tinkering in the automotive world. I did my homework and research and decided a SC 3.8 is the perfect platform for me. I have had some exerience with NA 3.8s but alot of this is new to me. Heres a basic setup:
Stock/All Rebuilt 00 Grand Prix GTP Daytona 500 with 4T65E-HD trans (Also Rebuilt)
I have seen what these cars can do and plan on building this one up in the high 300 if not low 400 whp range (eventually-durability with power is the key). I have heard that these transmissions are the weak point on these platorms as well as with the LS4's. Ive seen some upgrades done to valve bodies and Torque Conv's on LS4's but nothing gives any details.
Any good ideas on how to "Beef Up" this transmission to handle those power ranges?
Main Idea: Tighter shifting, wider power range, longer life span, quicker throttle response, and o yea...3:29 gears.
Any thoughts on the 3:29 gears would be helpful as well. Im not very good with FWD Transmissions, or rather dont have much experience with them, but I believe there is two ways to change the final drive of the trans to 3:29. Best way? Better way? Is it worth it?
Thanks guys, this is my first post on here, just to give you a reference of how new I am to this engine platform.
