Hi Lance,

Is the source code of the MShift versions some where available? I only found the binaries. I would like to implement the features for 45rfe support.
Whats needed is shift pattern per lever position, the logic for the shared TCC / LR solenoid and 1-n /n-1 shift logic because of the shared solenoid.

This will get us running at first. We have the engine and trans in the truck at like end of may to do some live tests.

kaputnik,

The 1.100 source code is here: http://www.msgpio.com/manuals/mshift/4L60Ecode.html

This is the recommended starting point for anyone wanting to write custom code. It has a minimum of abstractions, and is thoroughly commented. It compiles with the free 'special edition' of codewarrior. V2+ code requires the full version of codewarrior (which cost many hundreds of dollars).

However, you might also want to check to see if what you need is already in the V2 or V4 code, such as this: http://www.msgpio.com/manuals/mshift/V2tune.html#h

After reviewing the hydraulic schematics I have found no use for the OD solenoid to use the transmission as a 45RFE (66RFE and 68RFE have not been reviewed). This leaves a spare solenoid to use as the Converter Clutch solenoid. Would I be able to just install diodes in line on the two solenoid drivers to separate them since one solenoid operates both the LR clutch and the converter clutch? Do I need to separate the two circuits since there is already a recirculation diode for each solenoid driver?

There are five digital switches to determine shift lever position in the RFE series transmissions (45,66,68). Would there be any problem with installing a resistor on each switch and running them into one wire to make a voltage varying PRNDL like a Ford?

Jb426,

Yes, that's one way to do it.

From what I understand after reading the 41TE guides, nothing extra is required to separate the solenoid driver circuits as long as they are spliced between the recirculation diodes and the solenoid. Is this correct?
