Background: Some of you know about the fiasco I've had with busted transmissions in the last few years, not to mention the bad luck on the last few replacements that never even made it to a trail. In the past, I've had the rear bolts stripped and heli-coiled on one, and broken 2 other housings along with a bell housing (in the classic location). Part of it is my fault relating to the square shafts, bent/broken springs, one trip without my skid (big mistake) and getting too throttle happy. Finally got a good one (I hope) and don't want to break the housing again so I'm making some changes. First up, I have always ran a cross member only on the doubler adapter, which put it about 6" behind the 203 adapter. That kept it clear of the front shaft, and I figured it wasn't that far out of line with the factory 203, long adapter 205, and other cases, so that may contribute as well. And I guess GM thought that front adapter alone was good enough for the 203 with all the weight hanging off the back, seemed to me this was better than that.(?) Stephen and others think it also needs a front cross member for the 203 adapter, but then you have drive shaft clearance issues. Frankly, I think the cross member was not an issue, and every catastrophic break I had was due to bent/broken springs (allowing rear axle to move forward fast when the front spring arch dog-legged) or from direct impact on the 205 case. The plan: Part 1: My current plan is to build a sort of cradle that bolts solid to the doubler adapter and the 203 adapter. Then it will have a riser (sort of like a wall) that goes up the front of the 203 adapter and bolts to the th350 rear 2WD mount surface. So, that would tie all 3 mounting points into the cradle to help eliminate much of the load on those 4 little bolts, which are all that hold the adapter to that aluminum case. Then there is the matter of tying ot the cross member with bushings. One option for bushings is to use stock case mount bushings flipped over so the "C" is on bottom. Then the cradle mounts set in the "C" with the blocks on top. Or, poly spring bushings could be fitted close to the side of the case, with the bolt parallel to the frame rails. Either way, it would be midway between the doubler adapter and the 203 adapter. These mounts would support the cradle above a cross member built from 1.5 x 0.188 square tube. This, along with poly motor mounts, should flex well enough without being over stiff as they are (IMO) when located out by the frame rails. Considering the people who do get away with the wide spaced bushings, this should be fine. Part 2: You know those OE struts from a "K" or "HD" converter inspection cover up to the engine mounts? And the ones put on the FWD side of many 205s, 208/241s, and others that ran up to the bell housing bolts. Well, I'm thinking it would work better to run from the top bolts of the 203 adapter up to the 10 and 2 o-clock bell housing bolts. Maybe with a coupler nut or turn buckle to allow a bit of preload tension (or at least exact adjustment). That would keep the heavy 205 from trying to wag like a vertical tail, flexing the transmission housing till it breaks the rear off, and should take some load off the bell housing as well where it is so frequently broken near the top. Doesn't look like there is much way to do the same on the bottom, though it would be nice. Maybe I could find a way to run one or both up from my cradle to the bottom bolts? <shrug> Seems like the top would be most helpful anyway since the loads would be tension, and the cradle will help with the corresponding compressive loads on the bottom when you drop hard and hit something with the frame or something. What do you guys think? What about that cradle tied to all 3 points? It's going to have to be pretty precise to keep from putting too much pre-load on the trans housing. I have no mill or other precise machine equipment, so I figure it will need shimming (like a starter) at the least, or otherwise some built in adjustment of some sort. Or, maybe just a little preload and a 2WD poly mount? I don't think I want to go that route, thoughts?
