Installed a LU in the A413, definately worth it!

I think he moved on to modding different cars. I will see what he says.

Thank you sir,

I remember hearing that 600whp number too, but 600whp on a 2.0 might still be less peak torque than a 400whp 2.5..

IIRC DblTrbl also had a 9 or 10 sec neon with a 604. He might also have info on lockup converters.. since the small 604 converter and the 413 LU converter are the same thing.

I have the info on what Steve did to the LU shaft to make it survive, he said raising the line pressure past 130 or so would snap the shaft time and time again.

He polished and heat treated the stocker to get it to hold a 2.4 and 610whp and 475ft/lbs.

He used a billet kevlar LU converter sold by pats performance converters for $750-900

The more i read about it the more i want a 904 LU shaft and LU torque converter with 904 slines installed put into a a413

Ouch, that's a bit too much for me.

Nah, no reason why an aftermarket stock type A413 shaft properly built shouldn't work.

Last I knew Stephane made those in 300m 1st and were good to 600 or 800 whp, then switched to the 904 splines

Good enough for me,

Interesting, I thought the connector at the front of the SMEC was for the LU as it matched the LU pigtail I took from another van? Seems either it was a fluke or ? as I found an 89 Van with LU at the PAP today, ended up cutting out the wiring harness from the 60 way to the SMEC as I didn't feel like tracing the wiring at the yard, but it goes thru the white starter connector, into the main wiring harness, then to the SMEC and to a relay!

IIRC it's bundled up with the fan wiring , starter wiring and reverse/neutral switch wiring usually, and it goes to the front plug somewhere on my SMEC.

It is, hence what I wrote earlier,

[RoadWarrior222]

Ya, it sounded like you thought it was odd and needed confirmation

any new updates on the wiring for the LU Trans hookup, adding my toggle switch this weekend to my 90 spirit T1 it has to go thru the speed sensor somehow because it comes in at 45 mph I have been checking it out on my 92 shadow very close. driving 70 miles mostly highway daily every little bit helps

The SMEC turns the LU clutch on & off using engine load, RPM and speed to determine when. Your toggle switch does not have anything to do with the speed sensor. You will simply have to be diligent and flip the switch when you need to. I've been doing that for 2 years now in my GLHT.

If you wire it into the SBEC, then you can alter its change point but if you using a toggle switch like i am for now, you simply put one side to power, one to ground.

Shelgame has given me the updated ASM file for the SMEC with the LU routine enabled, just haven't had time to load it up.

Side note: Just happened to notice last weekend that the lockup was unplugged on my '93 Clam. Plugged it back in... wow what a difference.

Does it have a tach?

As an alternative to manually activating the LU, or having the ECU do it, you can use a vacuum switch from a 70s GM car, then just hook one side to an ignition switched power, and the other side to the solenoid, this is in addition to the toggle, only because it would still be on when you came to a stop. BUT, you won't have to remember to hit it thereby saving more gas since it would be automatic...

Well set the brake to cut it out, the vacuum to cut it in. That should work pretty good I would have thought... but would still take a little adaption, unless you're gently riding the brake at low speeds it could stall.

[contraption22]

No, not yet. Was thinking about checking the difference with my scanner tho.

[contraption22]

I wonder if there would be a way to tie a pressure switch into the trans to have it only come on in 3rd gear and tie that into the circuit?
