dev daddy, the rebuild kit for the ax is ridicoulous in price, and so is a rebuilt one, and most people want for a used one what a rebuilt one cost, sooooo......

 

So what about a 727 or a tf999? Either one could be found behind a 258, which would bolt up to a 4.0 no prob. Granted the 727 takes more power to turn like a thm400, but no electronics, and you have many choices of t cases.

 

Hmm what did a 727 come behind? Will my current NP231 bolt up or no? I dunno what a TF999 is

 

The th400 is not electronic...

 

Really, All I need is the Shift lever controller from RADesigns and toggle switches. I don't need a new wire harness or TCM for an auto to swap in the AW4,.... in my AX15 Cherokee?
If so my Auto swap just got a whole lot easier.

 

The th400 has an electric kick down. The tf727 would have been found in a full size jeep. Can't say whether or not your 231 will bolt to it. A common swap in an AMC eagle (which has a tf998, light duty 3 speed auto) is a low range case, some have used the 242, and I believe the 249 is the other common swap. Novak would have a definite answer on the 231 attached to either or. The tf999 could also be found I believe in cj7s.

 

is a 727 in about the same size range as a th350? I am also digging this aw4 shifter it's not what I thought it was

 

The 727 is a very compact tranny, shorter than a th350, as are the 998 and 999.

jp gives some specs here.

 

The th400 is vacuum controlled shiftdown... same as th350 and powerglide

 

Nope, th350 has a downshift cable, th400 is electric downshift. The th350 has a vacuum modulated upshift.

 

I know the th400 in my 74 truck has no eletrical to it

 

If you were to look at your case, on the driver side, right before where the shape of the pan starts it's 45 degree (or so) angle towards the tail shaft, there is an electrical plug. You may not see it from below, but if it's a 400 it's there.

 

x2 and the th350 will NOT hold up to anywhere near 800-900 hp. went through 5 on my buddys nova (built 406 stroker around 600-700 hp) broke two on the first burnout on the pavement, one lasted around a week, other two were built, one was built extensively, neither one lasted more than a month. just my 2 cents...

 

woahhhh you guys are going wayyyy too fast for me. I'm already lost now



either that or I didn't read on to the other pages.... good possibility

 

negative... my 70 impala did not have electronic kick down either it was cable 400/th400... my 72 chevy pickup had the 350/th350 which was cable... i pulled them both and installed them both myself... maybe some do? but not ALL... 700r4 started all the electronic stuff... but even it can be bypassed...
