drive gear problems-th350

When I bought my car, it had the tranny setup for drag racing, and had the hole for the speedometer driven gear plugged. I drove out the plug, added the drive gear (10 tooth tan colored) and retaining clip, the driven gear housing and drive gear.

All seemed good, the speedometer was working fine for the first few miles. Then nothing. I pulled the tailhousing off again, and the drive gear and moved and was loose even though the clip was still on it. I noticed the small nib on the clip and worn down a little. I bent the clip out to add more pressure when I put the drive gear back on. It was pretty darn snug, so I buttoned it up again. All was fine....... for a few miles, then it quite again!

I don't understand where on the output shaft this clip is supposed to secure itself to. The output shaft is smooth other than the splines for the driveshaft. So what keeps the drive gear in place? I know it is the clip, but is the pressure of the clip on the smooth output shaft supposed to be it, and that is all? If so, why does mine refuse to stay put? It seems there needs to be something else.

I might buy a new clip and try it again, but if it does the same thing, I am going to superglue that bugger on there!
Any help is appreciated

Try a new gear ( be sure it is for a TH350 and not a 700). They have a slight press fit so they are snug.

there needs to be a hole in the output shaft for the clip to hook into to properly retain the gear on the shaft.

in the posted photo is the common Chevy style speed-O clip (center of picture) to be used on a t-350 with the proper plastic gear.

This may sound dumb, but is there output shafts that don't have the hole? I did mine while the tranny was in the car, so I could not see the entire shaft, but I did not see a hole.

I hope I just over looked it. Next time I will take a flashlight and mirror and try and find the hole and line it up with the new clip. My clip is just like that except that little nub that I assume goes in the hole has ground down rubbing against the shaft.

thanks
