700R4 Gear “Hunting”

His problem is not isolated to the transmission. It's electrical also affecting dash gauges.. Run a volt drop test from battery negative post center,or center of side post bolt to engine block. Put a meter in volt scale 1 lead in center of battery post other lead on a goid ground,have someone crank the engine while you look at the meter. If it shows less than .5 volt your good,more than .5 volts you still have a ground problem. Not clean enough connections etc. You did run the negative battery cable directly to engine block didn't you?

I edited my post. The wire I am thinking of is actually on the gage/idle fuse. It might be purple down by tthe transmission, running on the driver side. I know because mine rubbed through from touching the transmission and I had an issue with my gage fuse popping.

Here is a link to my thread on the topic

Thank you both for your help. I’ll try and look within the week. At this rate I almost wish it was a “easy transmission fix” cause this is a pain in my ass. Grounds are ANNOYING haha

Where are you in Oregon? I can maybe take a look if you are close to Salem. Check your ground point on the parking brake assembly as well. All of your dash and gauge grounds are there.

I'm usually up there on the weekends either fishing or playing hockey. I can maybe swing by the next time I'm up there and see if I can spot anything obvious. Feel free to PM me and we can see what we can work out.
