dropping the t-150/dana20 need advice

T/C and tranny are very solid feeling. no whining, good shifts but very leaky.

T/C needs every seal redone.

The first question. I was planning on leaving the bell housing/clutch ect. on the engine and just pulling the tranny by removing it from the bell housing. is that what you would do?

Once i have it down should I only seal it or should i get a master rebuild kit and attempt that on both?

I keep going back and forth in my mind. my mechanical experience is decent but i've never been inside a tranny. I put a aussie locker in my last jeep to give you an idea of what i can do.

What say you?

I work by myself almost all the time. I have found it way easier to support under the transmission, pull the pan and pull the t case first. This makes the weight manageable and easier to line things back up later. Move jackstand under the belllhousing or engine and pull transmission. After the transmission comes out, YES I would pull the bell housing and clutch if for nothing else, inspection. Almost always its a good idea to replace the bronze pilot bushing. You may also find your rear main seal leaking too. The coolent could be a leaking joint at the manifold heater hose or a side block freeze plug.

Only you know your time, budget, and skill.....also the miles on the unit and if its needed. You may be able to get away with front input and rear seals. IF you open it, I would do bearings and synchronizes at the least.

I learned the hard way that the T150 is tricky and can easily mess up your day...how? The rear retainer is held in by the T case. IF you spin the unit by hand with the retainer unsupported, it will walk out, and small parts will fall...I got mine back together without a full disassemble, but others have not been as lucky.
