SW20 3SGTE gearbox diferences?

[Kender]

According to Toyotas TRD website, the gearbox in an '89-'92 SW20 3SGTE requires a different LSD part number to that in a '92-> SW20 3SGTE.

Are there any other differences between the 2 gearboxes, and are the 2 interchangeable?

The early box will accept an aw11 sc lsd unit. The later boxes have electronic speedo drives. You can use a later model box on a early model.

To add to Kender's question, are the housings interchangable?

I've managed to crack my 93+ around the LSD (long story).
I have a couple of spare 89-92 gearbox's.
Currently crack is covered in silicon to stop leak

Pureadrenalin, I think Al's saying that the housings are interchangeable.

The housings are not interchangeable, the gearboxes are, provided you also change the axles as well

The later model gearbox has the good dual cone synchros and the LSD as standard, the early model has the crappy sychros and no LSD standard. IME the early gearboxes all have synchro problems (typically 1st to 2nd), the later models have no issues with synchros.

so lets say i have a gen2 92 gearbox and i wanna swap it with a gen3 93 i have to have the gen3 axles????? both gearboxes are from the turbo model, i know that the gen2 non turbo has much smaller shafts, is there a difference though with the gen2/gen3 turbo shafts???

because if thats the case i NEED gen3 axles, hahaha

I changed from Gen 2 (Mar 93) to Gen 3 ('95 according to Mr Wreckers) without any problems, actually I can't tell what the difference is.

That's because there is no difference

What is the difference in the axles? Is it just the diameter of the shaft (phraw, that sounds rude) or are the inner cvs different as well?

Nope it's the length of the shaft splines

Later model LSD ones are shorter.

^^^^^
by about 5mm (check when I put my last one in.
If you put an aftermaket LSD in, they (all the ones I know) take both years axles.

Dam it. Now I have to find another 93+ gearbox. Anyone...... lol

man thats confusing,

so the gen2 turbo axles splines are longer than the gen3 ones meaning that the gen2 axles wont fit with the gen3 box???

huh?

No, the Series 2 SW20 (Prod date 12/91 Chassis # 0059266 onwards), has the same gearbox (with LSD standard) as the Series 3, 4, & 5 and therefore the same axles.

The only different gearbox and axles are the pre'92 Series 1's, which didn't have the LSD as standard, and had the longer axles that won't fit the other gearboxes.

[Kender]

cool. thanks fivebob. That last explanation simplifies things enough even for me to understand

[92mr2paddy]

ok, lol

im enlightnened!! haha cheers for the info!
