Smile GM 5L40-E Hydramatic (Optimizing / Tuning / Software / Maintenance)

Hello from Germany,

here in Germany the GM 5L40-E stands for:

- does brick under 75.000 miles
- bad design
- not able to handle the power from a 330d, 530d, 330xi
- no chiptuning
- oil change is required after 60.000 miles
- no rev-limiter change

I think that's not the true story about this transmission. I've read something here and there - and it's no secret, that the us-bimmers delivered with this transmission instead of the ZF-Part called 5HP19.

Here in Germany we are able to drive a little bit faster than our friends in the U.S. - sometimes 155 mph for one or two hours. Is that a problem for the GM 5L40 ?

I don't know - but with under 60.000 miles and a Oil/Filter-Service my transmission slipped through gear 2. gear 3. since the hard tour mentioned above...

I've heared about two or threee guys who are running a hpf kit or turbo-kit - amazing ...

A second point is, that the GS20-EGS-Module restricts a RPM-Limit-Tuning - the transmission will shift @ 6500 RPM - not at 6800 RPM or other Limit...

Is there a change to optimize the transmission by using other materials?

Seriously not trying to be a smart ass. Ok, maybe I was.

Not sure what you can do to an auto tranny without spending lots of $$$. At that point, just do a MT swap or maybe find a better auto tranny that will bolt up. But then I imagine you would need to do some software tuning.

Or maybe swap in the SMG tranny. Didn't the non-ZHP 330s have an SSG option that was pretty much a detuned version of the ///M SMG?

Yup he could ... it'll be easier than a manual swap.

email these people and ask if they could do anything with the 5l40e, the have 5l50 listed:

http://www.compperformancegroupstore...ionControlUnit

there were a couple of others, i'm going with the MSGPIO-based controller:

http://www.msgpio.com/manuals/mshift/index.html

but that requires some recoding for the 5th gear and such.

in addition, the a5s390r (aka 5l40e) is rated at 390 lb/ft of torque input by GM. used in a bunch of other cars including saturn solstice, cadillacs, v6 commodore holden, etc.

Or...you could stop dicking around and get a Cosworth GCU. If you want control of the engine and transmission in one package, the SQ-6 can do both.

And there's nothing wrong with that either.

I am working on figuring out the control signals to the steptronic with a data logger myself......

you don't really need to do that.
all the docs on the 5l40e are available. it's an electronically controlled trans.

3 shift solenoids, all the info is available on this, very little guessing.

News from Germany:

- we have now a "extra-module" which is able to control the TCC (Torque Converter Clutch) - which overrides the torque converter. No loss of power in the torque converter anymore - in gear 4 and gear 5, starting at 35 mph...

- if you get any slippage by the gm hydramatic 5l40-e, give the tranny more pressure




it's amazing, no slippage, no power loss, shifting like a SMG-Tranny, i think the shiftings are faster then any ZF-Tranny with optimized Software from ESS or something.

could you be a bit more clear? is this a separate module? is there a site with more info? losing less power in 4th and 5th would be a god-sent!

Exclamation

It's a seperate Module, connected with the following cables in the ecu/egs box:

- engine rpm
- gearbox speed sensor in
- gearbox speed sensor out
- tcc-converter clutch to gearbox
- tcc-converter clutch to ecu




Here you can see it working in a E39 - 530dA, with 193 HP - the Torque Converter Clutch is enabled at 45 km/h (30 mph or something) - and you never lose any power.

The module switches automatic to "SD" Mode under < 40 mph to keep the gearbox in a lower gear - but with enabled converter clutch.

With a 330XI, like my car, the tcc will be enabled at 65 km/h (50 mph?) in 4. gear and at 75 km/h (60 mph?) in 5. gear.



Working in a 330D E46:

not really... just had some engine work done and got a bigger bore with some over-sized cp pistons.

So, how does one increase line pressure?
What are the benefits on your extra module??

BTW, 65kph is ~40mph and 75kph is ~47mph.

First: It's not "my module" - i've only done the "alpha" and "beta" test.

Second: If you own a 325xi, 330xi, 330xd, 320d, 330d, 530d - you will know the automatic gearbox. You know, that the gearbox shifts a little bit slowly and the torque converter clutch is enabled at ~ 60 mph. Under this speed, you will stay in the torque converter - the engine and the gearbox are not connected directly. you stay in the torque converter and your car will accelerate like a elastic strap

With the module your torque converter clutch will be enabled at 40 mph AND in Gear 4 and 5 - not only in 5 like it's standard.

the increased line pressure will be helpful, becouse the clutches are pressed harder - no slippage or something. If a shifting takes 250ms in standard-conditions, a shift will take 125ms or something. It's like the ESS/Dinan optimized steptronic-software for the ZF-Gearbox - only better

If you have a supercharged 325xi or 330xi, you can use your higher torque and the gearbox will shift better...
