700r4 gurus please help
i rebuilt my 700r4 about 5k miles ago complete TCI streetfighter kit from summit,and new pump. everything new but the fuid,it ran fine. then on sunday i took it for a 100 mile road trip no beating on it at all, all highway ran great. woke up monday mornin and it would not go into O.D. shifts firm, does not slip at all and some times it does not down shift into 1st. but... if i manually shift it to 1st. it rips! then manually to 2nd barks the tires then third all good but wont go to overdrive. hmm.... dropped the pan, and the magnet was full of a silverish gunpowder looking material. NO metal shavings at all. installed new filter fuid and no change at all. what you think? it does not slip at all!!! i am thinking of removing tranny this monday and bring it to the builder to diagnose it. but would like more opinions. thanks

yes completely emptied it new clutches seals, steels, bands and removed the valve body. it is the master tci kit for 220$ from jeg and summit. new pump but the old governer could the valve body be clogged with that silver material? man i just swear the tranny just has some glitch cause it DONT slip at all when shifted manually. what does the governer control and do they go bad? would tv cable not let it down shift to 1st.? gurus help
----------
and yes it has a new tv cable, adjusted right

sorry didnt mean to blow up, yes the governor can go bad, the valve inside it can wear out and the plastic gear can get worn out. your manual first problem could possibly be that something is wrong with your forward clutch or your low roller, probably low roller since it is rebuilt, because when you put it in manual 1st, you are applying two extra clutches to make up for any problems that you might have, dont know about the o.d. because when you are in od range in third gear, your forward clutch is on and 3-4 clutch is on too. then when you go to fourth gear then the 3-4 clutch is used again and the band is back on. it could be your band because in manual 2nd, the overrun is also on to take up some slack. for fourth your band is on, so maybe if is having a hard time holding. just thinking of hard parts first, not valve body or anything like that

i am removing the tranny monday and bringing it to my builder for an autopsy.
would having a worn case cause this? my tranny builder said my case was a bit worn last time i rebuilt it. the amazing thing is, i parked it ran fine, then the next morning went to work and bam no O.D i looked at the governer the plastic gear is fine no wear but the other end i dont know how it works. and where is all the gunpowder paste looking material coming from.

mine had 150,000 for it was rebuilt, i had some of that powder too, pretty normal i think. the other end of the governor is a valve inside the shaft. of the very end are weights and springs that control when the car shifts. fluid comes in that valve and tries to push the valve and tries to get fluid over to the throttle valve, the weights and springs are what keeps the fluid back until it cant hold it back anymore then it makes a shift because the fluid gets to the throttle area then. its the got rule Governor Overcomes Throttle, the governor pressure has to overcome throttle pressure to make a shift. If he means worn out as in hard parts inside, yes that could do it. let me know what he finds

another question - did you change the apply piston seals? If you've got one screwed(either age or new installed wrong/harmed in any way) it may be bypassing to much to apply properly.
- There's really not a whole lot to "wear out" with the case. Maybe if you had a plantary out for a while and kept driving or something.....
- I'd pull the governor, pull it apart and clean the "apple core"

check to see if you can see the valve in the stem area move up and down when you pull the weights out on the end, the two levers are your weights, the pieces that the springs are touching

to the left of the blue gear, the section on lands and stuff like that, if you move the weights in and out you should see a valve move up and down. if you look thru the holes, and if it moves up and down u will see the holes dissappear and re appear

Ed, Here is a link to some preliminary checks and procedures that must be performed when rebuilding the 700-R4. You may want to just run through them to be sure that you didn't forget something. This is info used in an educational setting and specific to the 700-R4. Hope this helps.

ok i dropped the pan. checked the tv cabel all good ,checked the tv valve it plunges all the way in. like it supposed to. should i remove the plunger and clean it thoroughly? but...... i pulled the governer, and the inner bullet so to speak, it would not move in the barrel unless i moved it with a tiny flathead screwdriverit was all gummed up. so i remove the gear pin and with some prodding i removed the bullet ,cleaned it all out with carb cleaner and compressed air and sanded both the bullet and the barrel with 400 grit wet with wd40, now the bullet slides easily within the barrel before it wouldnt move when you shook it back and forth. now it easily slides to and from. i am soaking it in tranny fluid and will reinstall it tommorow after work. would a stuck governer have cause my problems? thanks ed

well, my new rebuilt governor went into office yesterday, tranny easily went into 1st. shifted to 2nd then 3rd all good. but would not go into O.D. stopped at a local tranny meca to ask advice.he adjust the t.v. cable then says, quote"go out on the intestate any nail the gas wot she will build enough pressure to go into o.d. ya cant hurt anything". so i ablige. 15 min. later and a little tire smoke and bam! she shifts better than ever, dead perfect.went back to the shop quote "prolly had some clutch material hung up in the t.v valve" moral to this story. change fluid more often.
