Yea...I wouldnt touch the EPC screw...it's like lighting a fuse.
Geno, my apologies. That's why I said the guy who's JMOD I did "told me" he paid for a baumann kit...if you saw the spring(s) that fell out of the lower 1-2 assembly, and the shims, you'd laugh yourself(double-coiled lower spring, like a racing valvespring...it was odd)...and gag. He told me it was a baumann. I have had NO personal experience other than that mess, and what he said. it might have been a trans-go....I dunno.
So, thanks to Ray, telling us(me) that the Baumann is basically a pre-drilled sep. plate, I fully understand now.
My apologies...you are right(did I just say that?) it WAS total BS.
anyway...JMOD< >Baumann< > apples to apples....

i beleive it is a trans go kit,sounds like someone put the shims in the wrong place causing premature brakeage.i thought the shims were supposed to go in the case first then the spring then the piston then the spring then the cover. im supprised that you didnt find more damage than that.BlackIceLSC said:

I would like to intersperse here...
I researched this to death Craig. It will suprise you how common the "aftermarket" Baumann kit is to the Jmod. I have the Baumann instructions in the garage I believe. I need to scan them and put them up for all to see. A lot of the Baumann "aftermarket" kit is drill bits and very detailed instructions in addition to common accumulator upgrades! Yes there are some other 'parts', but they are 'sonnax' from what I remember, a manufacturer of gazillions of tranny parts.
Mmmmmm... didn't your old tranny have the Jmod? I don't remember you saying anything about the Jmod taking down your tranny.

Inquiring minds want to know. Which came first, the JMOD or the BAUMANN kit?

As far as the EPC setting and advice not to tamper...
You can increase pressure or increase flow to achieve the same result. You CAN crank up the EPC and jack up the pressure and yes it will shift firmer. But you just increased the pressure on everything to effect one shift point. The more sensible way is to increase the flow by drilling out the particular flow paths of the shift you seek to enhance. The danger to cranking up the pressure too much is evident when you realize if you blow any seal or start to bypass fluid in a critical circuit, the pressure will fall dramatically and THEN parts will start to fail in a domino fashion. :steering

Carefull, JP. one must read the entire story before drawing conclusions. :F :soapbox: :bash: :N :joke
My car's tranny STILL has the JMOD. if the baumann and the JMOD are so similar, than wouldnt it be true to think if a JMOD can cause damage, couldnt a baumann?
However...the JMOD had nothing to do with the pre-mature failure of my 94's transmission. The failure was actually nothing more than worn forward clutch seal rings. They have since been replaced, along with a new stator support and I have a spare tranny for my buddy Joe's Mark. Totally irrelevant to a JMOD. In fact, this is a common problem on any 93-94 4R70W that has ever been subjected to extreme temps, or manual 2-1 downshifts. Since I havent owned my car since new, I have no idea what sort of life it had before me. But JMOD, Baumann, or even trans-no-go will have nothing to do with a forward clutch seal problem. (TSB#-96-24-9). This may be good news, or bad news for you, JP, with your early model 4R70W.
I think posting the baumann info would be good so others can see what exactly it is. But can I ask you...why does it come with drill bits, if it has a separator plate that's already drilled?
I'll stick with my JMOD's...they're free, they are proven, and I know enough about it to not worry.
In response to "what came first"...I would have to say the JMOD simply because this is how the transmission was ORIGINALLY designed. But they 'toned it down" to keep grandpa happy. Baumann/JMOD is simply putting it back to where it was intended.
a 'soft shifting tranny' simply means a tranny with a shortened life span. This translates into more profit for Ford. Plain and simple. My analogy is this: Imagine a 12 speed bicycle that took longer to shift between gears. You know, that clanking sound of the chain moving from one sprocket to the next? well, if it took a bicylce longer to change gears, that would cause pre-mature wear of the chain and sprockets. the smoother, and quicker the chain could re-locate, the longer it would last, due to limited wear, and slippage.

OK, when I get around to cleaning the garage(don't hold your breath, LOL), I'll dig up the instructions and scan them somewhere. Everyone can then decide on their own.
I say Baumann, you say JMod(almost sounds like a musical, huh?)... but the true sense of the matter is when you said "Since I havent owned my car since new, I have no idea what sort of life it had before me. " Now when I first pulled the pan on my '93 I was delighted to see how spanking clean it was. No sludge, no particles, no scum... clean as a whistle. This is an EARLY 4R70W, as evidenced by the "Do not Service" sticker still affixed. Good or bad, I have not been friendly towards AODs of any sort. My tranny could give up the ghost tomorrow, but notwithstanding the hard driving I occasionally do and 96 launches at the track last season, I try not to abuse the tranny. It is serviced faithfully and the fluid is kept cooled with a transmission cooler.
BTW, when I received my Baumann kit, it came without the pre-drilled separator plate, and included both early and late model valvebody gaskets. You drilled the separator plate with supplied drill bits to your own specifications as well as other details followed to your own specification. IIRC there also was one valve body spool valve replacement recommended for early models that was NOT included in the kit.
I did not mean to imply the JMod was the demise of your tranny, only to point out the absurdity of saying the Baumann kit killed a transmission. Bottom line, the JMod OR Baumann shift kit is only as good as the installation as well as both previous and subsequent service history. :steering

I'm going to leave that one alone. I have now heard from 2 reputable(and people I trust) sources that the Baumann is a legit kit. But the trans-go...I dont have any experience with it, but "if" the pieces I found came from a trans-go...I will NEVER recommend them to my friend or foe.
JP...yea, my tranny gave me no warning, but what happened was, I was hot-lapping it at the drag strip...I was rolling in drive from the staging lane, to the burnout box...I was doing about 30(the fat guy was cussing cuz we were going slow due to tire smoke blocking our vision). I didnt even realize what I had done. For some (stupid) reason, I yanked it down into low at a 30 mph roll. THIS is a major NO-NO in an early 4R, especially when its hot. I know for a fact, that simple manual 3-1 downshift at 30 mph smoked my forward clutch seal rings.
Funny though, the car hooked up fine on that pass. It was the drive home when the warning signs occured. Of course, the tranny was fine for weeks after, but you know me...I wont drive a broken car...I swapped it for a 98+ unit...I could have fixed mine for less, but why? a 93-94 4R70W is the weakest of them all. Poor main control design, roller OWC, etc.
anyway...I'm going to do some research on the Baumann. I might have to slap one into one of these 8 Mark VIII's we have, just so I can familliarize myself with more of the products Geno sells.
thanks guys.

i have a good friend who has had positive experiences with trans go in his aod's, so I am going to rely on his experience. I am not saying it's any better or worse than the baumann tho.
