    well yesterday my 700r4 took a dump....when it shifts to second it locks up and stops the truck in its tracks /forums/images/graemlins/crazy.gif
    what are some good upgrades to this tranny to help it?
    Also what are my other options for trannys that are stronger?

    A good rebuild kit for a 700r4 is going to cost about $250, it's commonly available and goes by the name SM465. /forums/images/graemlins/waytogo.gif /forums/images/graemlins/rotfl.gif

    Don't listen to the pedal and stick pushers. /forums/images/graemlins/wink.gif A th700 is a fine transmission for your application. First off in your sig I see 35's with 10b's. thats a fine combo also but do you know what your gear ratio is? I wouldn't want anything higher than 3.73's with 35's and th700. 4.10's or 4.56's would be better. There are TONS of upgrades for the th700 from mild to wild. I would bet with a stock 350 engine and your drivetrain(assuming you have an acceptable gear ratio) that a 700 with a good qulaity rebuild that includes an extra clutch pack in the 3rd/4th set, quality torque converter, good shift kit, and an after market sun shell....should be good enough as long as your cooling system is up to par. You should have the stock radiator cooler first and then into a secondary air to oil cooler behind the grille then back to the transmission. Beware of your local shops, some aren't worth a poo when it comes to a quality rebuild on a 700. Do your research and find out who seems to know the most and who has the best reputation. There are also other options like Bowtie Overdrives. i think their site is www.700r4.com /forums/images/graemlins/thumb.gif

    I rebuilt my 700r4 with the help from my brother and these are the parts that I used;

    1. New lockup solenoid kit
    2. New Alto Kevlar master rebuild kit with 3-4/9 clutch pack. It has the Kolene steels and the Kevlar friction clutches.
    3. New Sun Shell "The Beast"
    4. New reverse boost valve
    5. New 13 vane front pump kit
    6. New Torrington thrust washer kit
    7. New Torrington bearing kit
    8. New Boost valve
    9. New High Rev hardened pump ring kit
    10. New Separator plate
    11. New 29 element heavy duty front sprag
    12. New Billet Corvette 4th gear Servo with 35% more holding power
    13. New Corvette Servo
    14. B & M Shift kit
    15. New Oregon HD Towing convertor

    Look up OregonPerformanceTransmission on Ebay for the parts. He's a great guy to deal with and he combines shipping for multiple items.
