Hi all ,
It's been a year now that i have that tranny ( with 3.90 ) and it's a great daily driver . I have the v1.5 chip , Stebro complete exaust, but still, will need a complete forced engine made by LAN when he will make them availlable .. so , still waiting for that !!

how many miles have you put on it?

Nomad · #**138** 03-19-2009, 08:44 PM

About 14,000 Miles .

good deal, not sure if i recall correctly but didn't you elect to keep a stock spring in place vs. lan's upgraded spring, not sure what the spring was actually called or what it did, but having the stiffer lan spring caused shifts to be much more harsh....also i am assuming you had a tranny cooler installed, correct?

Nomad · #**140** 03-20-2009, 12:15 AM

No tranny cooler , I have the stiffer spring for now , but i'll change that to have a smoother ride , he's sending me it as we speak !

Great service by the way !

I used to ask people if they wanted the stiffer 1-2 accumulator spring and everyone always said yes, probably because they couldn't imagine an svx transmission actually having such possitive grab any of its shifts could be characterized as "harsh." I no longer ask and no longer use a stiffer 1-2 accumulator spring; I still have one in my car though. If you have stock shift maps and accelerate lightly and then let off there are times the car will be shifting into 2nd while you are letting off. With the heavier 1-2 accumulator spring that shift could be easily be characterized as harsh. With my shift maps that doesn't happen because you don't go popping into 2nd gear too early to begin with. With my current valve body modifications and the oe spring the shift is still instantaneous but could never be characterized as "harsh."

ha well , maybe i'll just change the TCU now ... I didnt know that it would resolve that little point ....

need to wait in April tough...

That is a good move, stronger accumulator springs make the engagement heavy all the time. It is better to let the throttle pressure ramp up the accumulator pressure to suit the torque that has to be carried.

Of course this will still be turned into a 'soft serve' by the TCU, unless a Quick Change is fitted to allow the box to make the changes the way the gearbox manufactures intended.

okay okay , I just paypaled Lan for a TCU ... So with his performance transmission @ 3.90 , and v1.5 , it should behave like a champ ? I'll post a note when i'll have tested it for a week or two ...

Common LAN , it's been 10 min already ...WHERE'S MY CHIP !!!??

I switch between SVX and Range Rover, but SVX is primary car. I drove from Orange County (NY) to White Plains at least twice a week in heavy traffic on Thruway and not a complaint about the tranny as a daily driver.

Since getting new tranny likely around 2,500 miles and no worries.

Hope this helps

i've put 1k on mine now...still wrks like a champ!

btw she is a daily driver....about 230 a week

longassname · #**147** 08-04-2009, 08:23 PM

these boxes are kicking butt and partial rebuilds are available now...so if you have an svx get one of these transmissions to turn it into a high performance sports car instead of a pending break down.

Has anyone pushed any HP through this tranny? As you know I have a level 10 rebuild. I would be interested in a shift map which would allow the engine to reach peak HP with the cams LAN sold. Anyone know where these cams peak yet?

I'm planning on doing a tranny swap next month, and though I've been leaning more towards a 5mt swap my budget and my workspace are not looking promising for a job of that caliber, so I'm researching all options at this point.

What kind of warranty do you offer on your partial rebuilt transmission? And do you offer a package deal if I were to purchase an upgraded TCU with it? Also, if upgrading to a 4.11 would I still have to change out the rear diff just as if I were doing a 5mt swap? If so, which car would I have to pillage to get the diff?

Thanks in advance!

I think you'll find the factory 3.545 gears are the best gears for the car once you upgrade your TCU. There is no package discount though and there is no warranty. If you were to put it in and it didn't work right I would have you send it back to me to redo it. That is very unlikely to happen.
