4l80e slip yoke
You can call Denny's Driveshafts. You need a counterbored 32 spline th400 slip yoke.
It should be a 1330 but they don't list one, you might need a crossover u-joint.

You need the counterbore to allow the yoke to slide over the shoulder on the shaft to maintain the proper spline/tailhousing bushing engagement.
Some 4L80E's and a lot of 4x4 transfer cases use the same yoke but fully splined. They don't have the o-ring or the shoulder that the counterbore slides over.

the gentleman does need a counterbored yoke, Denny's can get it for him, it is the TH400 for threaded output shaft yoke.
You would think with all the high speed trans vendors on this site, they would know this.
However,
Not all TH400's have an output shaft like that.
The truck units that used a bolt on yoke have a similar output shaft, the Denny's slip yoke will work on both the TH400 and 4L80E. The TH400 bolt on yoke is too short to use on the 4L80E in a truck application.
The older passenger car TH400 shafts are splined slightly further up the shaft and don't use the o-ring as shown. They use a regular, non-counterbored yoke.
The TH400 truck shaft has a raised ring around the o-ring area that will cause a regular non-counterbored yoke to bottom out. Hence the need for the counterbored yoke on a retrofit application.
