Well today on my way to work my transmission wouldn't shift. I have a 700R4 tranny that was rebuilt 3-4 years ago. I backed out of the driveway and when I put it in drive and got to around 10-15 mph. I was waiting for it to shift but the rpm's just kept climbing I pulled a u-turn then went back to my house. I didn't really get a chance to check it out since I was late for work. I just got home and wanted to know what the problem could be and what I should look for tommorow. the fluid level is fine.

When I was coming back to my driveway I put the car in nuetral and revved it up just to make sure I wasn't in second gear or something. My car was fine on Tuesday. I put a new thermostat in yesterday but didn't drive it so this happened out of the blue. I put a new filter/fluid in about 3 months ago and adjusted the tv cable about 2 weeks ago. Any help is appreciated.

 

Samething happened to me a couple of weeks ago. Except mine wouldnt shift into 3rd. I ended up having to get the transmission rebuilt.

 

That sucks. I hope I don't have to get mine rebuilt again.

 

check the govorner gear teeth

 

I have a 700R4 that has about 20K on it. Let me know if you're interested.

 

adjust the throttle cable.. specially if youve been working on it or near it,,,, chances are its needs to be adjusted

 

Got my replacement governor gear in the mail today. So I took the governor assembly out and it is infact the governor gear. Like half of it is gone Do I need to worry about the chunk missing? I don't see how be able to check around for it in such little space. Or do I just need to do a filter & fluid change and be done with it? And to get the gear off all I need to do is take that metal pin out and then I should be able to pull the gear off?

 

tap the pin out and install the new gear.

 

Ok one more question, the new replacement gear does not have a hole for pin to slide through. Is it going to be a press fit then?

 

It should have came with the hole already but you can use a drill bit a little smaller than the pin,install the gear and drill thru then install the pin.

 

Push the new gear in, and then drill through it, using the holes in the governor as a guide. You'll need a .110" drill bit. Be careful to get the bit oriented so that you drill through the plastic gear, and connect the original holes in the governor, itself.

Sorry I didn't see this post earlier. Many times you have a "no upshift" in a 700, it's the governor. It would've helped if it were in the "Drivetrain" section.
