Will this trans fit without altering the trans tunnel?
I wouldn't do it. The 999 has a low first gear and is totally unnecessary in a really light car like the A body. The 999 is a lockup style 904 3 speed transmission. It is not an overdrive. If your intention is to not use the lockup feature, there's zero reason to use the transmission.
Have you noticed a lot of the no prep guys are switching to lockup convertors now?
No I have not. I've been out of it so long now I wouldn't know where to start anyway. Is there a certain advantage they've found?
Don't quote me but I believe you will need to modify the tunnel and the crossmember/mount for a o/d as well as shorten the driveshaft. Use the search function for A500 transmissions. There are many threads about the subject.so, I am running a very mild build 318, and am simply looking for something with an overdrive that would be reliable and i don't have to chop the car u. if the tail shaft is longer cutting the drive shaft is not an issue. with that information, does anyone want to provide their ideas. i have read all of these, the majority of my driving would be mostly around town, but would like to be able to keep up with traffic on the Xway. This has a peanut rear end in it. Not a go fast, just a cruiser. Thanks all.

FRom what I've seen they pull harder in the 2nd 660ft and trap faster.
I've also seen them shake the tires hard at higher speeds.
So 998 and 999 are both lock up's, correct? (non overdrive)
Thanks Rusty. I wanted to get that clarified.Right. I don't know the minute differences, but both are lockup, three speed non OD 904s.
