Well I yanked my t56 and put in a th400 with TBrake. I never got a full pass with the t56 in the car always breaking something.

I have two qeustions

How do I get the spedometer working with my TH400?

How did you guys route your cooler lines? I have the canton pan with kickouts so I know I will have to get pretty creative with the cooler lines just hoping for some advice and maybe even PICS.

Thanks

Might want to PM Rich Krause or do a search....I believe he's discussed in detail his TH400 swap.

 

Where did you get your TH400? How much did it set you back? Thanks in advance.

 

You will need a reluctor and sensor, I can find the pn's later if no one else posts them but I am sure a search will also turn them up. I had a bit of trouble getting the speedo to read correcly and eventually reprogrammed using Tunercat, which has the ability to change more of the parameter related to the VSS than LT1_Edit. A board member also sent me a file which helped. It won't help you, 'cause it's OBD1.

IOW, you install a reluctor and sensor in the tranny, make the correct electrical connection so that the PCM is getting a VSS signal, and reprogram the PCM if it is not reading correctly. Maybe I ended up with the wrong reluctor and that's why I needed to reprogram?

As far as the lines go, it depends where your cooler is mounted, so I really don't understand the question?

I hope you are happy with your swap. I am still not sure I did the right thing and may switch back.

I'm using an OBD1 computer so that file would be a great help if you could send it.

I just called for a qoute on those parts the total is almost $250! I don't care that much about my speed does the computer? I just need to know if the car will run normal without the damn speedo working.

I was really just hoping someone had some pics of the cooler install and routing I plan to try and mount it in front of the radiator.

Thanks

I will look later (at home) for the file. My cooler is not in front of the radiator, sorry.

IDOXLR8 the trans and converter was about 2k New drive shaft, torque arm, shifter and other miscellanies parts 1k total a little over 3k.

Rich where did you install your cooler?

Thanks

My setup ...

1) Coan Racing Comp. Class TH400 ... $998
2) 3200 stall converter ... $469
3) Spohn Torque Arm ... $375
4) Spohn Driveshaft ... $325
5) B&M Hammer shifter ... $199

You add it up ... though I sold my previous Vigilante converter for $500 and 4L60 core for $200

Still looking for the file, I think it's on the other computer. Be patient and I will find it. You can spend more. My tranny was a lot more expensive, probably overkill. Billet this, aluminum that, etc. But the point is to make it bulletproof, right?

Rich Krause

 

you wanna sell your T56???

 

Sense you have a M6 computer it wont care what your speed is. Only the A4s care becasue they need know when to shift the tranny. I found that the 700R4 to TH400 swap kit from summit works with a 4th gen torque so you don't need to buy a new torque arm.

I am in the swap just under $2,000 with a built tranny(to handle 700HP) new drive shaft, 3400 anti ballon stall, B&M 3 speed plate, inline cooler, lines, torque arm bracket, M6 crossmember.

I am not going to hook the speedo up right now because the VSS I found for the conversion was $186, and that puts me over budget.

I can't wait to get the car all done, right now I am taking out all the H/AC/V and air bags.

Good luck.

 

I dont know how they did this but I believe Atlanta Chassis Dyno used the front ABS sensor for the speedometer. The guy I bought my car from said that the car would not run right if the computer did not read a speed. I dont know about that.

About the cooler lines. I have a TH-350 and used the push lock Aeroquip line. I took off the fittings that the the hard line screws into and put an AN fitting in the trans. Then I ran the hose around the frame to the front. I hate those hard lines. They always leak on me.
