The TSX 6MT swap thread

[CrackerTeg]

Kinda sounds like what I was talking about. Whenever you can elaborate some more, that would be great.

Swapping the Vehicle Speed Sensor does not work!!

I've done it on both TSX tranny swaps that I've worked on, and the speed difference is the same!

If you'll look at the DIY, you'll find out that the TSX's 6th gear and the Accord's 5th gear are the same size.  The only difference is with the Final Drive.  That's why the car sits 500+ RPM higher at highway speed than with the Accord tranny.  The cluster interprets the signal like it was the longer Accord FD and since it is spinning faster, the cluster shows what the accord's speed SHOULD be with a stock FD spinning that fast.  I know that's why it happens because the modifry module alters the signal going to the cluster because it's a variable resistor.  TSX and Accord clusters are not interchangeable so that option is out.  The only real solution at this point is the modifry module.  I opted not to install one because even though the cause for doing so is appropriate, it would be a nightmare to prove in court if you were accused of mileage fraud.  I'm a paranoid little kid and I know that I could prove why I needed it, I just choose not to.

I may just get over it and install one, but it all depends on if I get over it...

Skippy, you should install the Modifry Yellowjacket on your k pro harness so nobody would question that you tampered with your VSS.  I know you're hesitant to modify your VSS on your stock harness, but there are other legitimate reasons to tap your VSS.

Well I guess I get a big fat FAIL then. Oh well, I tried.

[Skippy]

It's np, cracker.  It's good that you at least got me to think about other solutions.

I know this for a fact how the speed is read through your speedo.

VSS reads the third gear rotating in your transmission. It then sends this signal to the ECU which then interprets that signal to a variable output in the cluster. When I changed over from AT, I needed to replace all of these in order to get the new correct signal.

Why this won't work for the TSX6MT in the Accord reading the correct speed.

- The final drive is different (and for that matter, the 3rd gear spline)
- It is not viable to replace the Accord ECU with a TSX ECU
- The clusters are not interchangeable

If you could do all of the above, then you could get the correct speed. HOWEVER, which is something I'm trying to do when I swap to the TSX6MT. You can get a TSX VSS which then routs a signal into your Kpro. Kpro will interpret the correct speed. From there, splice the output wire of the VSS signal into the cluster and you can do all of this without purchasing the Yellowjacket Modifry to do so.

I know this will work because my Kpro reads the correct signal while my AT ECU reads the incorrect signal. The rest is just splicing the wires into your cluster (or in my soon to be case, an Autometer Speedo!)

Good input Mike! I can't wait to see your new setup!!

i was thinking about a clutch, flywheel and lsd upgrade and was wondering if there was a specific lsd for the accord? arent all k-series transmission parts interchangeable? i was thinking about using an obx lsd for a rsx-s

[timot_one]

I'm pretty sure that most K Series transmission internals are similar and swappable.  Cham is running an OBX LSD in his 5MT right now and I know he has installed these in TSX 6MTs also.  I will ask him about this tomorrow when I see him.

thanks

this is really interesting shit.

[Skippy]

Try driving it every day..."interesting" becomes "amazing".

[cna]

wow 6 speed swap this is good stuff!

[Skippy]

Where have you been dude i've had one for like 3 years now...

[Jeff Likes Bagels]

This looks like a pretty extreme job for my garage (I don't have one, lol). I guess I'd have to take it to a shop.
