Will a transmission out of a Cub Cadet 70/1000/124/100 etc etc swap right into a Cub 154, or are the gears / bearings different ?
P.S. Im trying to eliminate my 1st / reverse gear noise in my 154 by doing this

I'm no expert on Cadet transmissions but they use a reversing gear on the input side that the Cubs don't have. Cubs reverse rotation at the finals - Cadets do not. So - no, not a direct bolt in. Here's a discussion about going the other way - Cub trans into a Cadet. viewtopic.php?f=2&t=80114

that makes good sense, thanks for the info. I would assume a transmission from a Farmall Cub would a direct bolt on though?

A Cadet transmission will direct bolt in a Cub or a Lo boy. All of the internal gears are the same, however, at some point in the 1970s, Cub Cadet transmissions had a faster 2nd gear.
The only thing that is different is that the pinion gear has to be swapped to the other side. Once you have the back of the transmissions open, you can see the difference. It is an easy swap.
The cub cadet transmission has an input reversing gear in a separate housing, bolted to the front of the transmission. This all comes off easily prior to installation on a Farmall Cub or Lo boy. As stated above, the final drives do the reversing on a Cub and Lo boy, so the input gear from the Cub Cadet tranny is not needed.

Excellent, thank you very much for the help.
would you by chance know if the gears are the same strength?

Bill, he was asking if it would bolt into a numbered series Cub. I am not familiar with those, so are you saying it will work with a 154?

Finals on the numbered Cubs are laid over at 90 degrees as on a non-numbered Cub Lo Boy. Should be a direct bolt in as gitractorman indicates.
The Gear shift lever on the 154 has a bend, forward, unlike the standard Cub with a straight shift lever. Some one recently posted about using the top cover from a Cub Cadet and placing it on his numbered Cub transmission - it worked.

It would be best to compare parts catalogs between the donor and the 154. Even a Cadet Original/Cub transmission swap requires changing/adding a few parts. The gears are the same strength for the early Cadets/later Cubs.
