installed 4l60e/ speedo not working

Just installed the 4l60e in the 94 suburban and the speedo doesn't work. It also doesn't shift. I tried removing the speed sensor for the tail housing but it won't budge. Are there any tricks to remove the sensor from the housing?

BTW. It doesn't shift either, I hope it's because the speedo doesn't work.

Thanks...

No speed-O data to the PCM.... equals no shifts.

Is this the original trans for the 1994 suburban?

No, they (builder) provided the rebuilt transmission. I still have the original tranny and sensor.

How would I go about removing the existing one without special tools? I removed the 10mm retaining bolt and attempted to move it around but no luck. I was afraid to use pliers and break somthing.

Any tips?

It's easiest to remove the tailshaft and pop the sensor out. The o-ring is what's holding it up.
When you have the sensor out put the tailhousing back on and make sure the reluctor ring is in the correct spot. Should be in the center of the hole.
Alot of the time the sensor will leak out of the connector and cause problems. To fix this, wash the sensor down with brake cleaner then apply sealer to the sensor where the two magnets are to seal the gaps.

the sensor can be a PITA to get out. As 50-chev posted one way to get the sensor out without damage.

Dee De Deeeeeeeeee..

I was able to remove the sensor and still didn't work. Then I remembered that I removed a fuse a few weeks ago and then bam.... While test driving I said, The problem has to be electrical, then ding......

Thanks for the tips.

Time to take it for a test drive to see how it runs.....
