[Mk2] [Turbo] Mr2 turbo gearbox? E153 LSD

[mid_mounted_monster]

hi,

i am a bit baffled here, i have a rev2 mk2 turbo (1992) and the vin plate says it have a e153 gearbox code, from drivng the the car i always thought i had a LSD but come on inspection of the box with the drivshafts removed i have noticed that there is no bar in the diff hole instead it has a division with a hole in it. Why i'm asking is that i am doing a rev3 turbo swap and the e153 provided with the engine which is original to the enigne has a fat bar through the diff hole like the one below,

and according to this it means it has a lsd.

hi, on an e153 box the bar through the drive shaft hole means it has lsd (different for na gearboxes)
on the plaque, it is the number after the e153 that tells you wether or not the original gearbox that came with the car had an lsd, on mine it is e153 735

Hi fellas maybe you can help me out here...
Today it was time for my brandnew transmission - which i bough over a user in USA.As far as he could tell it was a 95LSD tranny for the MR2.
Today we installed this thing and experienced some problems.
First problem was that the tranny was 2mm away from my big oilpan!Meaning - it aligend nice with the block - but on the oilpan side it was offset.As the tranny only uses those sensless 6mm bolts down there we only had to think about the one big m8 bolt..we had to use a little spacer between the gearbox-housing and the oilpan!we did not want to risk a damage here.serious - i didnt like this.

ok but to the big mystery we had..
I once bought 1992 -1993 driveshafts Turbo ABS - for LSD trannys over UK.
This stuff fittet my Transmission very good.Now as we assumed i have a LSD we turned those parts and the driveshafts did turn counter wise.Meaning no sync as awaited on a LSD type?!Next point was - that the driveshaft could not be moved without a big screwdriver (for turning the half assembled CV part) - i really hope - this comes from the not oiled brandnew condition!!??

ok so my mechanic has a gen2 tranny in his garage - we took my driveshafts over there and tried to fit them in to see if i exidently recieved a gen2 tranny instead of a gen3 tranny with lsd..
And guess what - my driveshafts did not fit his gen2 tranny!

So this is very confusing..because of the non LSD behavior and the point that i bought this new tranny in USA - we assumed it was a gen2 turbo tranny.But as my UK driveshafts did not fit on my mechs Gen2 tranny - there must be something extremly fishy here?!

i really dont know what the problem is- we cant find no partnumber except one serial number on this transmission.

i hope you guys will bring some light into the darkness!

regards,

you sure it is 3sgte e153 gear box? jap import?

the also have 5s rather the 3s?

usa never have gen3 and usa also make there own mr2 rather import from japan

so 95 still a gen2 depend make in usa or imported i guess

if it is usa box, i will assume they is imperial rather then metrix bolt

thats all i can think of

hi,
i found out that it seems to be that all LSD gearboxes were the same.
also my US gearbox had metric threads.

i read this :

The OEM viscous LSD will act like an open diff when
you turn the axles by hand. Its not until you build fluid pressure on
the diff will it actually lock the two shafts. If so you can look at
the bar that can be seen through the axle holes in the transmission.
That is what proves its a LSD transmission. If it has something that
looks like a washer with a hole it is not a OEM lsd. You can send me a
pic of what it looks like in the axle hole I can verifies what it is.

LSD axles WILL fit in US spec gen 2 transmissions but the NONE lsd
will not fit in the LSD trans. Then you have the difference of JDM
axles and US axles. There are some differences in the depth of the
axle seal on the "jack shaft" side of the Trans.



so i believe iam all good here with my tranny - because i have that metall bar inside - and it turns vise versa on idle.
