A while ago I ordered a transmission to replace the dying (later dead) one in my 1989 B250 van. I ordered the 727 assuming a big rig like that with a 318 would have the beefier transmission. My mistake, we had a van with a 904. The 727 is 4 inches longer than the 904, has a different size torque converter, and a different sized rear spline. a few bits of linkage is different. Now we have to go out and find a shorter drive shaft that properly connects to our new 727 and a new flex plate that fits the 727's torque converter size. We will probably have to modify some linkage as well.
So I'd make sure to get the right transmission if you want an easy swap.

spine is reference direction and spline is curve, but in GSD spine is curve passing through plane.
gears mesh with gears both have external teeth where as spline meshes with internal teeth .both are used to transfer torque.
The parts will only work if you use an oil pump that goes with the chosen shaft. In other words, one must use a 27 spline shaft with a pump made for 27 splines. And to use a 30 spline pump you must use pump made for 30 spline shaft. Then you run into the complication of 30 spline pumps are made for 1987 and newer transmissions which have an auxilary valve attached to the valve body surface. So you now have to go out an buy a 87 or newer trans case. Meanwhile the dollars are flying out of your wallet. Finally the torque converter is also matched to the input shaft. So to make a long story short. If you have a 82- 86 700r4 with a 27 spline shaft keep it the same, or if you 87 or newer 700r4 has a 30 spline shaft keep it.
Saves input shaft spline
the purpose of the spline is to support the weight of your head
It will either be a 28 or 31 spline. I believe that most open rear ends used 28 spline and the limited slip rear ends used 31 spline.
spline (= groove) = ranura (noun), ranurar (verb)
In the mathematical subfield of numerical analysis, a spline curve is a curved defined polynomials portions. A spline can also be a portion of wood or metal.
Spline goes into transmission or transfer case.
The front spline portion of a drive shaft out of a 400 trans is what you need. It can be installed on any drive shaft you have of proper length. U-joints come in many sizes and styles and are very common. 400 transmissions are getting old I would start looking in older out of the way salvage yards for a front spline yoke out of a 400
no.
