E153 LSD out of a 95' Mr2

My project 5s-gte (445whp) ran strong for almost 2000 km before i started getting a grinding in first gear... then i decided to shut some silly old man in his porsche 911 turbo up, happy to say he was no challenge.... downshifting back into first then rolling off on the next light... Well first became neutral....

And here's why:



Also managed to crack the casing... not sure which caused which lack of fluid destroyed the gear OR the gear caused the leak and fried the trans completely.

New project: E154F trans and caldina rear diff ..... i guess

Gen 3 E153 got weak synchros on 1st and 4th, Gen 2 E153 got weak synchros on 2nd and 5th
This problem can lead to wear on gears.

My Gen3 E153LSD didn't work well with synthetic tranny oil, it grinded in 4th and the 1st was hard to get in
So I changed it with pennzoil synchromesh and it is like a new tranny.

Try that in your new tranny setup, this lighter oil is like magic and offer a good protection on bearings as well: change it every year because it's dino oil and not synthetic...
You can also try to add a small cooler instead of the small recirculation hose in the base of the gearbox, which also help bearings a lot.

beh... i have been using penzoil synchromesh as alot of MR2OC kids suggest it.

It is very rare that I hear a E153 break on the gear and not synchros or bearings. If your synchros were good, this is abuse or front jumping or bad shifting. A gear like that can surely hold 800-900hp if you put power to it when it is fully engaged. E153 needs slow shifting IMO

If that's what happened to your tranny after "shutting some old man in a porche up" it sounds like he's getting the last laugh.

Just sayin...

You downshifted into first...?

...light turnes red, u brake and down shift into second, then come to a stop and put it in first.... then u begin to release clutch and go again(ligbht turns green).... u give it gas and release the clutch and ur still sitting there, throw it in second and ur off, at s lightly slower pace, u'd think people here would have more than a blane idea of what im talking about.... your just fishing cuz you have nothing better to do lol

it was the take off that destroyed it, Notice the missing teeth! may have cracked and lost fluid prior to this from heat, really have no idea no puddle in my driveway

BTW, if you have an older E153 looking for lsd, its up for grabs, going on FS soon.
