    i bought my tranny from them, but if you wanna go over what they did id suggest to just copy their modifications, bcuz they give a warranty and itll be voided if you open up your trans.

    I have to replace mine also. I've been hearing talk about a lot of high horsepower cars switching to the Turbo 400. Supposedly cheaper, a lot stronger, and it pretty much just bolts right in. What do you think?

    my car shifts like it is its job, like it should! High performance motor-why not a high performance transmission? It only makes sense. Here's the basic modifications done to it (although mine is a class 1 and has high alto clutches, increased line pressure, and better servos and pins than the corvettes...i think theres more to it but w/e)

    4L60E Product Updates
    SHIFT CONCERN UPDATES
    1) New boost valve and sleeve are installed in the transmission pump
    to prevent slippage under heavy throttle and delayed reverse
    engagement.
    2) To also help prevent slow reverse engagement the low/reverse
    checkball is removed since this part is prone to wear leading to
    reverse engagement issues.
    3) Modified pump slide with spacer are used to apply more consistent
    pressure which in turn prevents gear slippage.
    4) All individual valve body circuits are tested for accuracy and
    pressure. This testing ensures that proper pressure is achieved to
    prevent slipped clutches, 2-4 band failure and soft lock up which can
    be caused by inproper pressures.
    5) The TCC Control Valve, TCC Regulator valve and the Actuator Feed
    Limit are replaced and the bores are reamed because these high wear
    areas can lead to shifting problems as well as soft or no lock up
    conditions.
    6) The forward and reverse abuse plugs in the valve body are replaced
    to prevent cross leaks that can lead to delayed reverse engagement,
    3-2 shift tie up and 3-4 clutch failure.
    7) New Pressure Switch Manifold is installed because this part cannot
    be properly cleaned. This part ensure no wrong gear starts, and
    delayed engagements.
    8) New Pressure Contol Selonoids are used to prevent high or low
    pressure issues which can lead to harsh or soft shifts.
    QUALITY & DURABILITY UPDATES
    1) The latest design sun shell is installed. This design is more
    durable than the original design which could sometimes break and lead
    to no reverse or loss of 2nd or 4th gear.
    2) The return springs in the 3-4 clutch are removed and the exhaust
    port in the separator plate is enlarged which helps prevent 3-4 clutch
    failure.
    3) The torque converter is remanufactured using a state-of-the-art
    converter aligner/welder which holds converter runout to even tighter
    tolerances than OE. This prevents pump bushing wear and front seal
    leaks caused by converter vibration.
    4) High energy 2-4 band is used which absorbs more heat and has
    greater durability than a standard band.
    5) High energy 3-4 clutch pack and increased lined clutch and steel
    plates (from 6 to 7) are used for increased torque capacity which
    prevents premature clutch failure.
    6) Aluminum 1-2 accumulator pistons are used instead of the OE
    plastic pistons which were prone to breaking. This stronger piston
    prevents piston breaking which can cause low fluid pressure and burnt
    clutches.
    7) All new pump and case bushings are used which helps prevent loss
    of fluid pressure and in turn clutch failure.

    keep in mind this is after it is remanufactured-NOT rebuilt

    1994 Camaro Z28

    Mine basically has all the same stuff, but with near 500 hp at the wheels, it tore ALL apart!! I put a factory tranny w/ a shift kit in it this past weekend and factory stall just to cruise around on weekends, but I need something different for sure! I priced how much it would cost to get the 4L60 up to par, and it was $2000 just for parts. That's supposedly bullet-proof, but I have yet to see a race car at the track with a 4l60, which tells me something. It was a good tranny for a medium modded car though!

    The 400 is dam near bullet proof but gearing is alot different. also all the electronics would be different. and 400 you would have no overdrive gas where i live hitting $3.00 a gallon.

    theres a good sun shell called the "beast" for 4l60e also can use the 4l65e five gear plantnets i would also beat a check ball into 3-4 accumulater feed hole and if going to take the check ball out of low reverse feed i would drill a .030 hole in rear piston.... rpms over 5000 you may want to drill small hole in 3-4 drum so it doesnt centrifically<-?? push 3-4 piston burning up 3-4 cluthes.

    I recently got my trans rebuilt, and I had the "beast" reaction shell and a five gear planetery. Looking at the stock vs these pieces you can definately tell a difference in strenght. Also, a couple pieces were welded together and alot of the holes were drilled out for increase flow.

    A really good website that explains a lot of stuff about what the parts do and how much they cost is :

    www.eatmyshifts.com

    They appear to sell some really strong parts.

    I don't doubt you blew your tranny but I saw your car at humperdinks, 500rwhp out of a N/A LT1 without nitrous I call

    3 YEAR Warranty/36000 miles

    Get the class 1 performance trans ordered and you'll love it, only thing is you cannot modify or open it or else you void the warranty. Doesn't come with a high-stall TC either because they claim they damage things easily.

    So I'm a liar, huh? You got a big mouth! Just b/c you don't know how to build a car right, doesn't mean it can't be done. I didn't have my nitrous on the car the night you saw it, but I never said I didn't have one. I'll be at Red Line Raceway this weekend - bring cash!! By the way, 400hp on the 355 c.i. motor at the wheels, and I just put my nitrous kit back on. I'll race you off the juice, and so it's not as embarrassing for ya, I'll tie a rope from the back of my car to the front of yours and drag you down the track. There should also be an LT there has well over 500hp at the wheels N/A, his car spanks my daily driver set-up!! High school boys talk about dyno sheets, men talk about timeslips.

    ok lets talk time slips, lets see scans of yours. And don't go saying I don't have one or the only one I have was when my car was stock...

    Scan a driveslip - whatever! Let's see how this goes, I post one, then you say it's fake, blah blah blah. What time do you want it to say, I have photoshop like everybody else. Again, I'm at the track just about every weekend, so come whenever and then we'll talk timeslips. I must say though, being that you have 2 posts and they have both been to talk trash to me, I feel special!
