Just did the J mod. Followed the directions drilled the holes ok and re installed. This is how my car shifts...... 1st....2nd ok......3rd over revs uh oh...4th overevs going into it thats normal driving.........floor it I have no 3rd or 4th gear wtf!!! Help here please

 

Thanks let me know but even if it was like a dog hair or something it would work its way out or melt or dissolve in the fluid........All I know is I floored it and made tiny shifts 3-4......it sucked....I can still drive it I think but I do want to know what the hell is up....I cleaned it damn good brake cleaner+ q tips throush the valve body then lubed it up a bit before I re installed everything

 

dont know if this helps but here are some things i found when i still had the auto and wanted to do the jmod

I didnt remove any of the springs...but I was told it wouldnt matter...could this be the problem

 

Tranny threw a code P1728 Transmission Slip Error...which isnt a good thing because now I know I need to go into the valvebody again...grand...never going to do a J mod again I may just get a new seperator plate and not attempt this....Good thing is its "limp" mode so as long as I grandma drive it will be ok for now

Still need some help on this though

 

They are my directions and if something is wrong with his car then HE did something wrong.

Did you lose a check ball (you should have 8)?


Did you make sure you replaced the manual valve correctly?


Is everything torqued down correctly and in the right sequence? Did you refill the tranny correctly? Did you drill a wrong hole? Did you debur the holes you drilled? Did you mess with the overdrive survo?

You're supposed to remove the springs, but that shouldnt make a difference. And there IS such a thing as cleaning those parts too well and stuff not working right.

 

only thing I can think of at the time as it might be is the Manual valve and possibly the o/d servo. other than that I made sure the ***** were in and the valve body is clean, cleaned it with brake cleaner and q-tips. Maybe I can entice dustin to check it out with me.

 

You said you didnt remove any springs, so Im not sure why you would mess with the o/d servo.


I bet the manual valve isnt in the right place or you cleaned things TOO well.

 

If I cleaned things too well what would happen.....also I poured some tranny fluid into the valve body before I put everything on.......i'm going to say the Manual valve....I saw my buddy messing with it but didnt see anything he did wrong

 

i have a hard time seeing the manual valve being the problem.

 

Why is that? You guys did something wrong... Read through the directions and make sure you didnt miss something.

 

It wasnt him....I had another buddy work with me but I agree I dont think it was that after I think about it.......

This wouldnt affect the slippage thats going on and why I dont have 4th

 

correct it would make it be in the wrong gear, not slip.

thats an internal problem or elec. problem.

 

I may just take it in a get a good old fashion shift kit and let them deal with it....lol





Edit: I did a few test like TCCOA recomended like put it in 2nd at 50mph and if the power dropped to idle i'd have a big problem but power held which is good and that mean the problem is in the main control w/e that means maybe a auto guru can chime in here.

Heres the list.....
Improper band/clutch application pressure. (Doubt it)
Main control assembly gaskets damaged or bolt out of torque. (Most likely)
Main control separator plate damaged. (Most likely)
Main control solenoid stuck or damaged. (ehhh possibility but doubt it)
Overdrive planet assembly damaged. (Doubt it)
Overdrive band adjustment incorrect. (Doubt it)
Overdrive band friction elements burnt or missing. (Doubt it)
Overdrive band cylinder damaged. (Doubt it)


And I can get into 4th gear but its a really really ****ty way to get into it.

 

I suggest taking everything apart and redoing it.

 

I dont have to drive it for 4-5 days after this weekend so i'm going to take my time on it again and see what I can do

 

I just saw you're getting a new separator plate. Did you drill the wrong hole or something? Id like to see the old one.

 

I havent taken it apart yet. I have a shop that is going to help me out since I fill my nitrous bottle there ALOT. So I will take the old one out and try and take a pic for you. I have a wierd feeling that its a drilled hole. Because I can get into 4th gear when the fluid is cool but when it gets hotter no more 4th gear

Hell could be that we messed with a spring or a check ball got stuck. Could be a lot of things right now. But doubt its any thing major

Also out of curiousity how important is the squence of torqueing the bolts?

 

Hmmm, get that picture for me.

 

none really i always just got them snug and then did the star pattern. its doesnt really matter. what matters is the valve body is clean,no metal shavings,all ***** and springs in place,and gaskets arent ripped.

I have done a good number of valve bodys never had a problem as long as i take my time.

 

Its very important. In fact, when I called PI to get some help with my converter problems, they asked me to make sure my v/b was torqued down correctly which it was. All of those steps in my directions are there for a reason. If its not torque correctly, then fluid could get in places it shoulnt be getting into. When doing this, the only bolts you dont need to torque exactly are the pan bolts.

 

i dont belive it, i have done over 10 ford 4r70w valve bodys its really not that important. just snug them them go back over them tighting them up. If it was i would of had a problem because of it.

 

You are giving out wrong information Dustin. Go ask Jerry, Alan, Darrin, Johnny Langton, Adam, Matt Hill.... Its very important to torque it correctly. It needs to seal correctly just like anything else with a gasket.

Look at post #13 by dirtyd0g, http://forums.modulardepot.com/showthread.php?t=89630

 

Easy boys I'll be torqueing the bolts to spec did last time and I will do it again. New plate will be here tomorrow.

 

UPDATE:

Problem still is there I had a pro do the J mod successfully. But still having the issue of the O/D light flashing and going into "failure mode" after a few minutes of driving there is no 4th gear after doing some research were thinking we have a electrical problem here. I dont know where to go from here i'm this close from parting it out and getting a truck. It's VERY AGGRIVATING. I hate this transmission. Worthless piece of crap I swear

 

tr3650? waddya say?

 

If you guys dont have anything productive to say I dont want to hear it. I'm not in the mood
