which manual trans for amc 360 + dana 300

ditching my torqueflite 727 for a manual - whats my best option, with cost a consideration..my plan was a sm465 with some adapters from novak..will a jeep T15 bolt up/no adapters? are there any jeep/amc manual transmissions strong enough/worthy that would mate with a amc360 & dana 300?

Depending on how hard you plan to wheel it, a T-176 would be a good transmission to consider.

or a T-18 with the Granny first gear would be a good choice if you planed on wheeling it very hard.
Restoration = lots of $ & time thrown at the jeep. I know we all know this but it helps in the process to keep things in perspective.

The T176/177 will bolt up with factory adapters. It is a medium duty "true 4 speed" with very nice road manners and pretty good strength. I run a T176 behind my 360 and used a 4:1 kit in the D300 to get a little better gearing offroad (with a 33" tire and 3.73 axle gears). It's a nice street/trail setup.

t176 and t18 are good choices. The 18 is super strong but basically gives you a 3 speed for normal driving due to the low first gear. Great for wheeling though. I drive my 7 with a 304 on street to run into town and what not and I am looking for something like the ax15 or if I had the money the NV4500 to get the over drive, with my gearing I am turning way higher RPM's than I need to be for the v8 on the highway with the direct drive final.

If you like the sm456 then the T18 would be a good choice.

I'm in the middle of a t18 swap in my cj. The t-18 is gonna drive like the truck it came out of, an 84 f250, but that's what I expect so its good. I also wanted the granny low and since my axles are 3.31s I never used 5th gear anyway. I also like the fact that I could stick a 428 cobra jet in front of it and not worry about the tranny

Would an AMC 360 with a Dana 300 and a SM465 be a compatible and stout setup. I plan to run 44's front and rear, and the vehicle will be street, with some mild wheeling. Just want to make sure I have a stout drivetrain, that I don't want to worry about breaking stuff if I do get into some harder stuff.

T-176/T-177 either one will bolt up to your D300

T-176 is a lot more street friendly. SM465/T18 are truck transmissions with 3 street gears. Lacking in the gear department for highway, you gain a very handy low gear and a bullet proof trans. The 176 would be the more economical way to go as it was originally bolted to AMC engines and the D300.

While I like the SM series, when using an AMC engine and bellhousing, the swap is easier if you go with existing transmissions that will fit. These include the 150 three speed, 176 four speed and the Ford or Jeep version of the T18.
The 150 and 176 are Tremac (Ford) medium duty transmissions that were offered stock inn the 76 and later platforms. They have given years of good service behind Ford and AMC V8 engines.
The T18/19 gives you two choices of first. The 6.3 granny low transmission is basically a three speed with a compound low for offroading. This is a great transmission if you are having problems getting slow enough through technical sections. The Jeep/Ford T18/19 also comes with a 4.0 first gear. This is a much nicer onroad transmission (If you could use that term with any T18) and gives you true four speed gearing. The great thing about these transmissions is they are a virtual bolt up to the existing 76 and later bellhousing. Do a search on the Novak sight. They have a huge knowledge base on these boxes.

i've had both the t-18 (4.0) and the t-176, the 176 is by far the way to go if you're going to use it on the street much. Around here you can find t-176 d300 combos a lot easier than you can find the d20 or t-150 or t-18.
