Ive got a 95 bonny SE...the other day i backed out of my driveway and started driving down the road when the check engine light came on it wouldnt shift and the speedo didnt work so i turned around and pulled back in popped the hood looked around for a little and notice that i blew a hole where the speed sensor is...i saw a little piece of gear...that part of the tranny that the sensor goes in looks like it unbolts from the rest of the tranny now i havent taking it apart yet but does anyone have a diagram of how that looks inside there and also that piece of gear i found does that connect to a shaft that goes into the tranny or what do you think it goes to....oh yah there was also no loud bang no clunking when i left and its been running and shifting fine also just rolled 111k

Please post a picture of what you have. From the sound of it the speed sensor came out of the DIFF cover. The gear your seeing is part of the sensor.

Read twice.. there'* a piece of a gear in your hand? Not good, you probably need a new differential and cover.

If the gear is in the trans.. you may need to just bolt the sensor back in place and or replace just the diff cover.

Overall...odd though.

Here'* some pictures of the diff.







Does any of this help?

Whatever you do.. don't pull the diff with the shaft attached like the last picture. Thers'* a plastic lube dam to help lube the diff that breaks when you pull the main shaft from the passenger side instead of the driverside.

Very true. That transmission was being gutted, so I pulled it that way.

ima need a new diff cover theres a good size hole were the sensor goes....the gear i have is the smaller pinion gear its in 3 pieces...i dont have it apart yet i just put it on jack stands and i could look and see the damage...ill try to get pics up to better explain

and the pics do help thanks...can i pull that main shaft from the pass side

Sounds like your diff came apart and took out the cover. If that'* the case, find a local pick and pull yard and grab what you need.

You can, but don't. If your very careful the locking rick will slide past the oil dam. But if you brake the oil dam, your taking the transmission apart because the oil dam is right in the center of the transmission. this is it.


So pull the diff, remove the lock ring, and pull the output shaft from the drivers side. But, you really don't need to remove the output shaft to change the diff.
