700r4 stuck governor

[260z]

Been told I may have a stuck governor on 700r4 transmission, how can I check this, fix. Thanks

Stuck? I doubt it. If it was stuck it wouldn't downshift - you'd have high gear - Why don't you tell us what your symptoms are? Governer pressure opposes TV pressure. If TV pressure is higher it forces a downshift or delays upshifts based on manual valve position and range. If governer pressure overcomes TV pressure upshifts occur.

The most common problem I see is either the gear becomes aplle cored and you have no upshifts or the spring lets go. If you think the valve is stuck in the governer pop the cover off and pull it out. actuate the centrifugal weights and ensure the valve moves freely.

Thanks for the help so far. This is all new to me so I will descibe what I have found out so. Manually shifts into gears, once in will not upshift but does not slip when in gear. Drained fluid, bad, light blackish light film in darker than normal red fluid. Broke up old filter, no metal but black in filter, soft breaks up easily if rubbed between fingers.
 
I took off the governor cover, was hard to see inside since tranny is still on truck. Felt around with finger to try and find any gears and the governor came out, (I hope this is not a problem) The worm gear and governor look good, the little arms on the governor have two little springs that did are not very strong. One appeared to be stronger then the other.

 Did not force but did try to easily install the governor back but could not get it to lock in. (if this matters) Moved in and out fine. Everything on the governor appears good except for the 2 little springs on the governor arms, they seemed/look a little weak. Since the tranny is still on truck it is hard to look at inside gear. I try a mirror to see if I can see anything.

Only reason I mentioned struck governor is I called a couple tranny shops to get a price on problem/rebuilt and one of them mentioned a stuck governor. Thanks for the help and bear with me I'am new at this. Any books/sites you can recommend. Thanks again!
 
Oh I adjusted the tv cable but not sure if I did it right. Pushed in release tab, pulled slider towards carb. Released tab, opened throttle full open from carb and released.

There shouldn't be any tension onn the governer springs so don't worry about it. If the gear on the output shaft and the gear on the governer are fine and the valve moves it's not oyur problem. You may have your TV cable too tight. After you adjust it actuate the throttle to wide open throttle (engine off of course)  and see how it does.

Turned the governor arm under a little pressure and does not slip so I assume the inside gears are fine. Gears on the arm are fine. If I move the arms the valves work but do not fully open, open less than half way. Is this normal. Not sure which output shaft to check. What exactly I'am looking at,thanks.

As far as the tv goes the slider is all the way against the cable holder, metal piece that holds TV cable. Can not be pushed towards firer wall as it is alright there.

So I push the release tab (works very hard) and tried pushing back but like I said it is alright against cable holder. Release the adjustment tab and pull wot. I'am not hearing any clicking noise when I try to adjust. I read some were you should hear a clicking when as cable automaticly adjusts.

Pulled slider out a little (away from firer wall)when thur adjustment and slider did not move. Pushed release tab moved slider back towards firer wall, released adjustment tab wot, no movement not hearing any clicking. Cable does move the valve arm below on tranny and the spring inside the valve moves so I assume the value is working.

Thinking the TV cable is bad? I hope all this makes sense, let me know if it doesn't.

it almost sounds like the tv cable is not connected inside the tranny or the cable is broken inside the casing, undo the cable down on the tranny and see if it is hooked to anything. If i remember correctly mine has a small pin that the cable hooks to

I couldn't really understand what you said.  lol

Sounds like it's adjusted too tight. Loosen the cable a little and see what it does.

Cable is connected inside the tranny and works. I still have the transmission cover off and checked. TV cable, I've tried everything to adjust no movement, finally sprayed with wd4  and it clicked out 1 notch when adjusting.

The release tab goes in really hard, I think I need to replace tv cable. There is also a slight angle between carb hook up and tv cable mount. From studies I've read this is not good, should be a nice straight line. I will have to correct before installing new cable.

I guess now I need to replace cable and mount so it's in a straight line to carb. Adjust tv cable put in new filter,fluid. Only guestion I have is the governor is out, is there a way to secure it when I put it back in tranny? If I install in tranny I can turn it in but turning it outwards it just screws out. Does it just hit the governor cover or is there a way to lock it in?

The drive/driven gear teeth mesh and keep it from walking out of the unit with the cover on.

When to junkyard so I know what you are saying. Governor,valve and output shaft fine. TV cable has been taken out and lube works well. Need to fill with fluid and and adjust tv cable, if that does not do it must be something internal. I will let you know what happens.Thanks!
