Disaster bummer. Exposed everything and found the differential case broke off at the bolt. (of course this is after foolishly buying new transmission mounts). My nephew used to be an instructor and Wyotech and said it would be hard but thinks he can weld it, and add a metal plate for more reinforcement. If we do it I'm going to have him reinforce the other side at the same time. I'm going to do some more research to see if this has ever happened to anyone else before. I googled '986 differentials' and nothing but a 5speed came up. Any advice would be well received.

Never seen that one before... Have you hit any roadbumps or something that you're aware of?

Something must have been wrong with another mount(s) I can't imagine that such a small aluminum tab with such tiny gussets would be designed to hold so much weight that the motor would drop 2" if it broke.

Is that where the L-shaped part of the tranny mount bolts? If so, is the top bolt of that L-shaped bracket missing? That's the only way I could see something like that happening.

Emerald, this happen to one of my X1/9 transaxles (where the slave mounts on the tab on top), took the gearbox to a friends shop and they welded the aluminum tab back again and with the extra welds seemed stronger than originally, and never had an issue afterwards, but I had to remove the transaxle to be properly welded..

I had one those in high school! Definite chick magnet, but tons of problems!

Wow, broken transmission case. That must have been quite a hit. That tab is part of the front half of the transaxle assembly including the bell housing and differential housing. I am wondering if the mount bracket or upper mount bosses are broken as well. To do that right, it will have to be removed and disassembled. At that point, you might consider just replacing the whole transmission.

Yikes...sorry I led you down the wrong road. I’ve haven’t seen this failure before. Is that an automatic transmission?

[jaykay]

Wow so the case broke right where the trans mount bolts up? Apologies, never thought about that. That explains the angle
