Getrag F23
Overview
The F23 is considered to be the successor to the Getrag 282 and 284. It is another 5 speed transmission from Getrag that was available in a few FWD GM delta platform cars.
Similar to the F40, this is a 3-axis design which differentiates it pretty heavily from the 282 and 284.
This transmission is basically the successor to the Getrag 282 and it is very strong like it.
The standard gear ratios that you will find out there though make this swap less tempting since most are going to be around a 3.94 final drive ratio since the cars these came in were 4 cylinder engines.
Strength
It is known to be quite strong based on a few posts across many forums, but evidence is a bit hard to find. It is rated for 170 ft-lb of torque, but like most Getrag transmissions it has been known to handle significantly more than this. Some have even claimed it is stronger than the F40 transmission.
How to Make it Work
You will want to start with the F23 that is made for the 00-02 Cavaliers and Sunfires with the 2.2 non-dohc engine because it's the only F23 that has the correct bellhousing to match the 3800.
This transmission is the successor to the Getrag 282 and it happens to need the same clutch modifications that the 282 swaps use. So you can use a spec clutch made for this transmission or use a clutch and flywheel combo made for the 282 swap.
These swaps involve a machined flywheel though if you are going to try to figure it out on your own.
There is a facebook group dedicated to talking about how to make this swap work in a w-body. At a minimum you will need special axles, and a driver side transmission mount that would work for the swap.
