I agree MOST have a tab or some sort of attaching device. This one dosen't. there must be a tool to get behind the gear and pull it off

Yep I have the item in the picture but I don't have the electrinics to make my cable driven speedometer go... Ihave the new gear to install just can't get the old one off. the trans came out of a 89 chevy pick-up.

After a little thought I remembered an old trick I learned back in machinest training about 40 years ago. I first put a punch mark on the gear then put a rag in the housing to catch chips. I then drilled a hole in it. I then drilled a larger hole through the first one. The gear split (YES) I removed it cleaned up the mess, and heated up the new gear in a can of oil. This is to not have it get bigger in one spot more than the rest. I slid the new gear on and finished putting it together. One more thing off my list. Thanks for the help guys
