Side cover leak
Thanks AJ, appreciate you taking the time to share your knowledge and experience. It's helpful! I'm pretty sure the leak is coming from side cover, the only place that's wet is the bottom edge of the cover. I suspect the gasket tore during installation, or was it was paper that needed sealant (vs. the Brewer's no-sealant gasket). Good to hear side cover can be pulled without dropping the trans, I've got nothing to lose by trying that first. Really rather not pull the trans again (sigh). It's an iron-case 833OD. I picked up a transmission jack last time I pulled it, made the job easier and safer since I don't have a vehicle lift. Good tip on on the guide bolts for the bell, though I'm hoping I don't need to go that far this time. I made sure I have the right gasket this time and will pay extra close attention to the placement of the bolts as you suggest. Much obliged!
