For those wondering why I'm making a build thread just for a transmission, it's just to keep from making a bunch of threads for the many questions I will likely have over the next week or two. Now with that out of the way, I was talking with a guy about various parts I would need and was told that when you start making a little power...you have to use a reverse manual valvebody. The reason I was given was, the factory valvebody will not generate the line pressure needed to keep the clutches alive under high torque/hp loads. While that did make sense, I don't know enough about transmissions to say yay or nay. I just wanted to verify from a non commissioned source.

 

Thought I would post up a couple of before pics...just for kicks. And yes, I'm going to sheen it up.

 

Following. What kind of set up are you going to run?

 

I'm interested in this because a TH400 will be my next mod. I am tired of running 10s in a 9 second car.

 

If you mean transmission setup, I'm not exactly sure yet. I'm trying to avoid the manual valvebody. But I'm not sure if it will live with a standard one. Im really not interested in shifting all the time, so I'm hoping I can just use a good shift kit and be done with it. If you mean car as a whole, it's a 2000ss turbo car....makes 770/900.

 

Should be fun. I am just beginning to research auto transmissions. I am running a t56 currently and am thinking about making the change

 

Yea, I hear ya. Could be worse, 11.33@137 here 😂😂. Automatic truly is king if performance is top priority.

 

I will be doing mine sometime next year, I still have some TEA CNCed TFS245s to put on over 317s to make more power. Then with the TH400 I'm hoping to get a mid 9 out of it.

 

Just my opinion, but I believe your car is good for a mid 9 and beyond without so much as pulling a valve cover....with just a 400 swap. If I remember correctly, you are already putting down mid 800s right now right?

 

That's what the dyno says yes. Could only run 10.80 @ 138 with it though but that could be just launching in no boost.

 

For what it's worth, and I witnessed this with my own eyes. I met a guy with a car like ours...2000 f body, was slow just like ours for the power it makes. Told me the best he could do with the 6 speed was 10.80 @137. Simply installing the 400 with no other mods to the car......9.13 @149. Putting down continuous power for the full 1320 pays off....

 

Wow that's nuts. This just makes me want to do the swap even more. I am going to keep up with this thread so I will know what I am getting into. Good luck with it.

 

So, the first in a series of boxes was found at my doorstep just now. I'm all about customer service, but they got this to me FREAKISHLY fast. Just ordered the shifter, cooler....and Transbrake. Flywheel was ordered as well.

 

 

Just got another knock at the door.

 

I'm in the same boat as you brother. Good luck on your build

 

Loving the pictures Soloman! Let us know how she does for you, I think you are going to be really pleased with that setup!

Hey man if you don't mind, and if you do I understand, could you give me a round about price range you are spending on the parts? A total would be fine. I am needing to see what I need to budget out to get this done.

 

I don't mind at all. PTC converter was $1022.35 and here's the rest. I screwed up and got the kit without bands. Whenever I get around to tearing this transmission down i may have to get a rear band. Not sure if it's cheaper to buy the band separate or in a kit, and I say "the" band because you won't use a front band when you do your trans build. Oh, and I still need to get the lines, will probably do that locally. May want to tack on another $150 for lines and fittings.

 

So no one is going to listen to me anyway, thats usually how it works.

Why did you buy that sprag? I'd bet a few hundred that your core trans has a roller clutch and you need a drum which you could buy off ebay for about the same price. If you buy a performance direct drum it's going to have a sprag and race.

The TCI kit, has bushings.....TWO the pump and tail housing.
I'd also bet money you could reuse your steels.

I payed a non sponsor $204 for Raybestos frictions, moulded pistons, gasket and sealing ring kit, transgo high temp ring kit, bushings (all of them), washers, filter. All name brand. AND FOR A 2006 4L80E!

Your TCI kit is a refresh kit, no internal bushings, no washers, no torrington bearings, etc.

Not trying to be a dick but someone has to speak the truth and not get all excited over pictures of boxes and parts you don't even need.
