1G 5th gear swap...more questions

[4gfun]

I asked some questions in the past here about a 5th gear swap and now I have some more since information is extremely disjoined on doing the swap.

I have pulled the .666 5th gear from a working 1g AWD transmission to put into my ..741 5th gear equipped 1g FWD 91-92 styled transmission.

I carefully set aside the 1g AWD 5th gear (and associated parts not pictured) in the order that I removed them.

Pictured below are all of the parts that I removed from my 1g FWD transmission. (Yes I know that I chipped the lip on one of the gears but I used a bearing puller on the AWD transmission so the gearset is not chipped.

I have no idea what some of these parts do and I generally don't care. This has not been my first 5th gear swap on a FWD transmission (different vehicle) but I did a quick and dirty swap with no issues.

I'd like to be a bit more careful with this car and make sure the swap is very simple.

My questions are as follows:

1) Can I simply swap out all of the parts pictured with the ones from the above mentioned working AWD transmission or do I have to/can I use anything from the old set?

2) Can I mix and match any of these parts? If not, which ones can I not mix and match?

These are my questions for now.

Thanks

Not 100% sure about fwd vs awd but you may find differences in synchro diameter and oil rail location. That will play a role in what you can swap and what you cant.

Another concern about the size, later model gears are larger, to make clearance for them, later transmission have slightly larger outer cover. If you look at the chamfer at the op of the tranny case, you will notice that they are different (late trannies have smaller chamfer and therefore more space on the inside).

Thanks for your thoughts. I have walked away from this project for a bit, but now I am back. The gears would all be from a 1g. I have a bit more understanding of what each part is (or at least is called) at this point.

Everything looks like it will fit physically and the rear cover (outer case) does not seem tot be an obstruction.

I still have the same above questions though.

If you are using the same size hub/slider assembly and synchro diameter it is a direct swap. The big thing that would run into clearance issues is if you are using a larger diameter hub and slider assembly associated with a later model version as your 5th gear cover curvature would run into clearance issues. This should be straight forward if you are using the same style gearset from the AWD into your FWD.
