Anyone ever use the Transgo 340-HD2 shift kit? Just bought one going to install.
Update to first Post:
Things you'll need to do this mod
Edit: I just counted the amount of bottles I used. I used 7 bottles. So you don't necessarily need a full case but you might as well.
Optional:
This mod changed the whole dynamic of the stock auto transmission and I highly recommend it!
Old First Post:
Just received my Transgo 340-HD2 shift kit in the mail. It cost me roughly $130. I heard good things about Transgo from other forums.

It's a kit that you use to modify your valve body in your automatic transmission. From my understanding you have to drill new holes in your valve body. It also comes with new springs and ball bearings.
The Transgo kit should make the auto shift faster and firmer. This is exactly what I need for my nitrous install. Once this is in I'll try out a 125 shot to see if it solves the issues people were having with the auto not shifting fast enough when using this high of a nitrous shot.
I already did the 4th solenoid ECU mod for the transmission that eliminates smooth shifts and launches and it definitely makes a difference.
This is a good video showing a Transgo install on an A340 tranny.
Except for they screwed it up which makes me kind of scared!
Anyways let me know your experiences with the Transgo kit on the a340. I searched the forums and it seems no one has used this kit on an sc400 yet... or just didn't post about it. If this works it could be a cheaper alternative to the more expensive $600 shift kits that are offered.
There is also a guy on the supramania that offers a valve body rebuild. I emailed him and and he said he could do the SC400 transmission as well. His price is very competitive. http://www.supramania.com/forums/sho...ation-services
Anyways my installer is going to take care of this install for me. I'll come back with feedback after it's installed. My only worry with this Transgo Kit is that the a340 is used in a wide range of vehicles (even jeeps) so I'm wondering if this will be an upgrade at all for our SC400's.
Things you'll need to do this mod
- Transmission Pan Gasket ( I bought mine from Red Alto but you can buy it anywhere. I bought the full A340 gasket kit from Red Alto but you can just order the trans pan gasket seperately).
- 12 Liters of TIV Automatic Transmission Fluid (You can buy this direct form Toyota. Mobil 3309 is also 100% identical. Don't buy anything else besides Toyota T4 ATF or Mobil 3309. Toyota T4 was cheaper for me, but if you can get Mobil 3309 for cheaper it's the same thing)
Edit: I just counted the amount of bottles I used. I used 7 bottles. So you don't necessarily need a full case but you might as well.
Optional:
- Transmission Filter I bought the ATP Transmission Filter. I got mine at NAPA but I think I could have got a better price online. The stock filter is metal and can be cleaned with brake cleaner. However I would recommend changing it while you already have the transmission open. The stock filter, even though is metal is 20 years old. Might as well buy a new filter. The filter is not expensive ranging from $20-$60. I bought the ATP one over another brand because the other brand was rumored to use a Cork style gasket (Wix). I'm not sure if it was true or not for the A340 filter they make, but the Wix filter was considerably cheaper. I decided not to take the chance and bought the ATP. I'm sure there are other good brands too.
- Valve Body Gaskets (1 for on top and 1 on the bottom of the stock metal valve body gasket plate) You don't necessarily need this because it's metal on metal so no gasket is needed. Up to you if you want to put them or not. I didn't. I'll just put them if my transmission starts leaking. You can get a gasket kit from Trasngo which includes every valve body gasket for every model of A340 transmission that exists. The Red Alto complete A340 gasket kit also comes with the valve body gaskets (you can also just order the valve body gaskets separately from them).
This mod changed the whole dynamic of the stock auto transmission and I highly recommend it!

Yeah this is the DIY you're referring to. Except the DIY doesn't explain how to modify the valvebody this Transgo Kit does.

. And I thought that just by upgrading the springs on the valve body would be enough ....

So now I'm googling what parts I need.
I called Lexus and they said I need these two parts.
35443
35434
I'm gonna keep searching and see if those are the parts I really need. Then I'll order.
Going to be waiting on the gaskets to arrive which will take at least a week. So I'll be getting it done sometime next week. Definitely will keep you posted.
I also bought another SC400 1993 for winter! So I can maybe even race my car against it to see the difference lol.

I actually brought it to my installer today to get it done and I forgot that I had to buy valve body gaskets! DOH.

So I called Lexus to order the Valve Body and this time I gave him my serial number for my car and he wasn't even sure now what parts the gaskets were (before he just searched by model year). He gave me some photos to figure it out by myself but I didn't want to take any chances.
Inside the Trans Go Box it says if you can't source any Valve Body Gaskets you can just order them through Trans Go. So that's exactly what I did.
The part number for the Trans Go Gaskets is 340-VB-G. This kit contains 17 different gaskets for every A340 variant transmission. So I'll be sure that it covers my kit. It was $34 + shipping.
I also talked with a technician on the phone and he said the kit should work fine with the SC400. I also told him about the 4th solenoid ECU mod and he said he doesn't recommend it. He said I'll get the firmer shifts that I want out of the Trans Go kit alone. My 4th solenoid ecu mod is already wired on a switch so... I'll test it out anyways once the Trans Go kit is installed. KC95SC400 has a modded valve body and the 4th solenoid mod and he doesn't seem to have any problems.
Update: Still waiting on parts. Hopefully going to get this mod done on the 20th if the parts come in.

Ya me neither! I've been searching the **** out of the internet researching on stuff for my car... and stumbled upon this. I found a few posts on trucks forums with people using it for the A340. Other than that one person on the supra forums bought the regular transgo kit and not the HD2 (I believe the HD2 Transgo kit has firmer springs and the valvebody mod).
I was thinking about just putting shims in my transmission but this transgo kit also contains extremely tiny drill bits (from what I understand) that you use to drill into your valvebody.
http://www.naxja.org/forum/showthread.php?t=1088057
"There are a couple of holes which are drilled and you have the option of 'truck' or 'race car' shifts." Just read that on that link. I'll definitely choose race car when it's getting installed lol.
An update on my install. So I finally brought my car to my installer this morning and he started working on my car. I had an oil leak somewhere that I just noticed last weekend when driving hard with a car meet from Montreal to Ottawa and back (and I was driving pretty damn hard lol). The car would smell like burning oil once in a little while. My installer checked it out and apparently my transmission was leaking a litte bit. So now my transmission has to come out to fix whatever seal is leaking (to do the Transgo Mod you wouldn't need to take the transmission out).
I was planning on ordering a Lextreme Torque converter this week anyways... but since my transmission has to come out I decided to order it now. Before ordering I checked ebay for fun and I found an Edge Racing Torque Converter for an SC400 for $400 + shipping so I jumped on it. I'm guessing it should be better than the Lextreme TC but who knows.
So my car won't be back on the road until' next week... just waiting on the Torque Converter now. I'm also trying to source an LSD/Torsen for my auto but it's hard to find one at a reasonable price.
Update: So the shift kit is going in this week! I'll report back with news as soon as it's done... Also ordered some surprises... A suprastick and an IS250 steering wheel with paddleshifters!!!! 10/10/12

I'm not sure of the condition of my gaskets. But from what I read it's recommended to buy brand new gaskets. Don't re-use your old gaskets.
