i doubt anyone is going to do that.... especially without having a tuneable controller to make the trans live.
yes they do. but a working controller is key to all the hardware. there are a large percentage of folks on here that can do hardware and mechanicals.... the electronics are the hard part for many.
im a facilitator by nature. i desire to find a working combination of parts that most can obtain and put together to make their combo work..... even if mine doesnt run.
hence why whenever i got info on how to tune these things, i taught as many people to do it themselves as possible.
its also why i hassle you from time to time.... :) cause you have the info and i want to spread it around. :)

I'll see if any Mexican controllers remain here......
Re: 41TE/604 operated by Megasquirt
I am lucky in that all the cars I care about the 604 for have factory 604 cases (3.3/3.8, 3.0, 2.4).
Re: 41TE/604 operated by Megasquirt
I have started looking for a 2.2 TCM and I'll also take pics of the Mexican 41TE bell housing, for reference.
The location change for the starter bell is the item of interest - many of the mounting bolt locations should be carry over from the 2.2 to the 2.4.
Re: 41TE/604 operated by Megasquirt
If I get a TCM from a newer car, like a '99 300M or something, would it work in my '91 Daytona with the 3.0 V6? Or are the inputs different due to crank triggers vs distributor? I think the only inputs on the early ones are rpm, vehicle speed and TPS, is it any different in the later models? Does it matter at all if it's 4 or 6 cyl?
Re: 41TE/604 operated by Megasquirt
Yes they're different. The pinouts of all the tcms changed right about ~1996 even with same engine. Also, I dont think the newer and older ways of determining shifter position (range sensor et al) play nice so i'm not sure you can use a newer TCM unless you also use a newer case that uses the newer style range sensor.
I still have my 97 Intrepid Autostick TCM. I planned to adapt it to my 1990 3.8L Dynasty.
Re: 41TE/604 operated by Megasquirt
If something was modifiable and standalone, I wouldnt worry about what wires it needed, I would obtain. I can't use a system when I have thrown away stock for aftermarket EMS. I do know that Syke tuning can modify the late 90's transmission stuff but you really need a complete factory wiring setup.

At this point, Syked Tuning only covers 07+ transmissions according to their website.
Re: 41TE/604 operated by Megasquirt
I can personally tell you that Syked absolutely can do JTEC back to at least 1998, and that DOES include transmission controls. My truck beta tested their handheld with FRP doing the tune. I stood there and watched. Ryan changed the lock-up scheduling and a couple of other things.

I was aware that they can do JTEC and now SBEC3, but didn't know that they could do transmission control. That's good news since my 2.4/41te Omni is running a 02 Status harness. Would be nice to be able to make it shift firmer and quicker.
Re: 41TE/604 operated by Megasquirt
OK, so apparently JTEC transmission control and the car/van transmission control are a bit different. I know it can do SRT-4 stuff, so I'd imagine PT/GT, but I don't know if that does in fact cover the transmission control. I will try to find out.
Re: 41TE/604 operated by Megasquirt
I contacted Kevin and he said he isn't going to support the eatx controller. So no 41te support until NGC.

The JTEC and SBEC's will not control the 41TE transmission.
The JTEC and SBEC's were limited to controlling the partially electronic transmissions (31TH LU only, 42/44/46/47RE, etc..).
In cases where the fully electronic transmissions (41TE, 42LE, 45/545RFE, etc..) were used in conjunction with a JTEC or SBEC; an EATX controller was present to manage the transmission.
Re: 41TE/604 operated by Megasquirt
Somebody mentioned installing a potentiometer in series with the output of one of the transmission sensors in order to increase line pressure. Do the 41TEs have a line pressure sensor? Could be a simple way to firm up shifts quickly when needed.
Maybe instead of tuning the TCM, we could fiddle with sensor outputs to trick the behavior of the TCM...

With adaptive adjustment it doesn't work that way.
For example:
If LP is increased the controller will still have a desired level for shift control.
This may produce an immediate 'good feel' but it will be followed by the adaptive control re-adjusting to gain nominal control.
In short, it will be short lived.
It's no different than the aftermarket engine controllers that feel awesome out of the box but go soft when everything settles.
When this occurs, they lack proper cals to support long term satisfaction and goals.
Re: 41TE/604 operated by Megasquirt
I see what you mean. It makes sense.
Re: 41TE/604 operated by Megasquirt
Well, in case someone is looking for an answer.
41TE support is officially removed from MegaShift software.
Actual codes are removed.
http://www.msextra.com/downloads/dev...pre-1-1-beta1/
41TE No longer supported supported in the official release.

Re: 41TE/604 operated by Megasquirt
No surprise there...unfortunately...
Re: 41TE/604 operated by Megasquirt
i never really paid attention to what the development of megashift 41te looked like or who was involved.
im guessing if there were more knowledgeable folks working with the MS guys and making sure they programmed it based on the patent docs and stuff, then it may have gotten off the ground.
truth is, the 41te is a pain in the --- even if it has good strong hardware.
with few working on reverse engineering the controller over here, it may never get diy tuning control.

Re: 41TE/604 operated by Megasquirt
For a drag setup the PCS controller can be used. Do they list it on there site? No. But it can be used since your under a WOT condition constantly.

I didn't think the PCS was even made anymore?
Even still, yes, it can be used, but it requires constant fiddling from what I remember the few people who used it saying (NSRT-4 guys). It doesn't have the capability of adapting to the wear, so it has to be done manually.
