Re: Tranny / tcase problem

So I have a TH350 with the 205 case and the side bracket is there and rubber is worn out on side mount. I replaced the transmission with a new TH350, installed new energy suspension mounts to the crossmember and put the side bracket back. should I remove the side bracket? can the adapter plate hold the transfer case? Really? remove the side bracket or get new rubber for it? my 4x4 is mainly a street wheeler and never got off road

thanks guys

Matt

Re: Tranny / tcase problem

I think this thread already answers your question. Ditch it! The transfer case will be just fine by the adapter itself. I always removed the side brackets when present. Cracked a few adapters in my time, I was hard on them tho. There will always be the argument of "yay or nay", just like Ford vs Chevy.... Well not on this site its NOT!!!

Re: Tranny / tcase problem

Just thought I would add this in here... my brother has a 79 bronco with a 205. It's driver side drop. It has a side mount. Not too much different than the ones we have on our trucks.

Fords bust transfer case adapters too.

Re: Tranny / tcase problem

How can you tell if your transfer case adapter is cracked? I can't see one but when I come to a stop a hear and feel a clunk under my floor.

If yours was cracked, you'd be dumping oil on the ground. With 150 lbs hanging there, once it cracks it's falling off

The thought of driving around and having that happen gives me chills. Another reason to like my divorced case.

Re: Tranny / tcase problem

DirtyLarry,
I am new to this forum and also to trucks predating the 2000s. I also realize this post is ten years old at this point butttt... I have recently redone my drivetrain. 69 Chevy with a 350, SM465, NP205. Im putting it all back in now and wanted to replace the rubber in the mount on the side of the Tcase-Frame. I have now read through multiple threads on here arguing wether to use this or not. I hear your argument to not use the mount but I see in your photo that you have a crossmember that runs under both your trans and your tcase. I only have a crossmember under the trans. This means that if I don't use the frame mount with my Tcase the only thing holding my 205 in there would be the 8 bolts to the spacer. Is it okay to have the Tcase hanging there in space by only the eight bolts? Suggestions? Thanks!

Re: Tranny / tcase problem

IIRC, there is also a rod (for lack of a better description) that attaches to the side of the T Case and ties into the back of the block at one of the bell housing bolts. This should give some support to the T case while allowing the engine, transmission and transfer case to move as one which takes the stress off of the bell housing and the trans to T case adapter.

FWIW, I run a divorced 205 and have not had to deal with the issues that you are asking about but have read much of the arguments for and against the side mount. If I were to run a married set up as you are, I'd run the rod support and ditch the side mount. Just my .02$.

Re: Tranny / tcase problem

I don't even have 4wd and yet learned something new from reading this thread. I was going to attach a second cross member to my NV4500 and folks said not to. So, I didn't. Now I see why.

Re: Tranny / tcase problem

Do the 205's run the rod, thought it was only the 203 cast or the 208, 205 has the side mount, I would run the mount if it came w it or make the rod work as mentioned, less stress on it for sure especially if the tire size is increased over stock or abused like I do, I call it driving it, haha.

Yes you will be fine just using the crossmember with the adapter bolted to it,that is the way they came from about 1973 on up, no side mount
