DIRECT BOLT tranny swap help

I asked this question once before but need to ask again.
I have an 85 CJ7, 258, dana 300 t-case and a problematic T-5 tranny. Rather than bring it back to be fixed again id like to invest my $$$ in a better tranny. Im lookin for a DIRECT BOLT tranny replacement that is better than the t-5. I know Jeep used several trannys over the years. Cant I just use another one like the T176 or the Jeep version of the T-18. Im not up to a fancy swap that requires adapters, major mods or major $$$ right now I just want to drive it this summer (mostly on road use) I dont need anything that is bulletproof...just need somthing better than this sissy little T-5 that keeps breaking down.
I just cant believe that with the common 258 and Dana 300 there arent simple options.

As far as I know, only the T4 and T5 are direct bolt ins. The others require a different xfer case or adapters or mods. The Mustang tranny will work but the gearing will not be what you are looking for. There are WC T5's specially made for your application. They are $2k plus.

Even if you go T18 and a Dana 20 you will probably need new mounts, skid plate, and drive shaft mods. Also the floor holes may not be correct.

Others can chime in and correct me if Im wrong.

jeep daddy...thanks for the response....not what i wanted to hear but you are probably correct...My other thought was to get a donor CJ with a 258 and swap the tranny and t-case but I didnt know that I might have to Mod skid plates and drive shafts ect. Anyone else know anything about that??

T-176 will work with your current transfercase and belly pan, but you will need that bellhousing. 2 bellhousing were used, one for the T-4, T-5, and SR4, and another one for the T 176, 177, and 150's. Both bolt up to and AMC 6 or 8 Cyl, but they have different trans bolt patterns. The T-176 will have the Dana 300 pattern on that end. You will gain some strength, and this is the least "effort" of a swap.

So if Im reading this correctly I can bolt the T176 right in from my donor CJ using the 176 bell housing. No drilling and tapping or drive shaft mods. Is that right??

you will probably have to cut/lengthen drive shafts. Or if you find a T176 just buy the driveshafts for it too.

Sampson9dk,

Check these people out. I have one of these transmissions, and can't wait until I get my jeep done. I talked to them a lot and they told me that they would warranty it even pulling my 20 foot boat. They also told me that they would stand behind it even if it was mounted behind a Chevy 350. Here is the URL:

Hope this helps.

Kevin
