I am currently considering a trade with a freind of mine. He wants my T56 and has a MW 3200 converter with a stock 4l60e. The transmission is having some problems so if I do this I will be having it built. This will not be an even steven trade of course. He will be giving me some boot.

My questions are: Will I have any problems because I have a M6 PCM and have no way to control the shift points? Or will I be able to remedy this when I have it built?

I need a converter that will flash about 4200 or a little more. Will i be able to get his restalled? Or would I be better off getting a new converter?

Any one running A 4l60 with a brake? Do you have any problems? ever wish you went with a th350/400 instead?

Sorry for all the questions but I figured this would be the best place to ask

Thanks!

First thing to consider is the fact that most of us are junking out our Bastard 4L60's to go to TH350-400 setups. The 4L60E is a pain in the *** for most people...it can be built....but for lots of $$. I have gone through 4 rebuilds due to 3-4 clutch pack failure....and jsut today....dropped the pan again to start the rebuild all over again. 1 week ago....my 3-4 clutches gave out again. These are upgraded Alto clutches as well...so, it's not a stock setup.

Regardless........you can build one......not very cost effective. You already have a M6 PCm program so you could swap into a Turbo400 without worries of the PCm trouble. Swapping to a TH400 requires a M6 program flashed onto your PCm if you are a auto. If you are going to go from M6 to 4L60...then you would have to have a A4 flash done to get your tranny to funcition.

Basically, to make a 4L60 work in your car...you have to have your PCM flashed for a A4 program. Then it would need to be tweaked i am sure to shift well. No way around this......there are alot of electronics inside the 4L60E.

If you go Turbo 400....then you get yourself a 400 built......buy the parts for the conversion...and go. With your PCM you have now......no changes.

Alot to think about.......as you can tell....i am not a 4L60 lover.....that is for sure. I have had nothing but problems with mine...and i also run a Vig 3200 converter.

Thanks man! This is what I needed to hear. I was considering the A4 but figured it would be more trouble than it was worth. Looks like a 400 with a brake is what I need. I will have to change out the 4.33's for some 3.90's out back tho.

One more question. I have heard that a 6.0 truck flexplate will allow me to run a th400 style converter. Is this true? Does any one make one of these flexplates that is SFI approved?

I do know that if you go to a 6.0 flexplate that you can stick with a 400 converter....... That is what i have read...although i am not 100% sure. Not sure on the center of the flexplate to the converter...i know the bolts line up though. Somebody else should chime in on that part!

Glad to be of help....beleive me though.....a sotck/lightly built 4L60 is a ticking timebomb!

Why does an A4 car need an M6 flash if it runs a TH350/400?

So that it is not lookinfor input from the tranny sensors. Yank sells a pcm tricker that does the job. Not sure of the price.

Exactly, if the A4 program is still there and you are running a TH350 - 400........the car will not be seeing the shift solenoids and such and will be very "confused". Basically it will not be getting info it would typically need to work properly. A M6 car does not have those sensors and such...so it is the program of choice to use......that is all.

Was really curious about the "tranny tricker" that you speak of.........didn't know something like that existed.......that woudl eliminate the need for a M6 flash. Checked Yanks' website and finally found it listed...they want $250 for the tricker if i read it right. Jsut some info for you all.

P.S. My tuner said he will flash M6 into my pcm for $100.

No need for all that tranny tricker stuff, it stores codes unless you have them deleted but the car will perform with no ill effects. My 94 runs the same with an M6 or A4 program. And each one it shows the same 3 codes....but it still hauls!!

So, your saying that a person could have a A4 car then swap to a TH400 and not do any programming....and the car will still work fine...other than the check engine light being on?

...thats what i'm thinking......

If you have an M6 and want to swap to an auto, DO NOT GO TO A 4L60E. I am on my 5th "built" 4l60e. I am going TH400 now. You already have half the work done for you - no need to reflash the PCM, no need to track down a M6 console, etc.
