LOL.

Very interesting that the slider exploded rather than the gear teeth shredding off. Significant sideloading on the slider? GL on the new gearbox.

 

mine did the exact same thing with a hard shift into fourth at 8k with roughly 400whp

good luck with the new boxes man!

 

holy jesus... that's heart breaking!

 

what I am worried about is that it wasn't a hard shift.. I just do not shift like that..

what I'll try to do is magnaflux the broken ring, see if it has any more cracks, and do the same on a old ring from one of the two gearboxes I bought.. I suspect is that since the ring has teeth on the inside, the inside edges make for a nice stress point where cracks start.. high temps on the tracks do not help..

I will use everything from the second, low mileage, gearbox

broken diff pics to follow..

thanks for the wishes..

 

WOWZER'S I blew up a few trannies before but wow thats a lot of carnage!

 

If the slider was defective then there is not much anyone could hae done to prevent this.

Also what fluid were you using?? I have heard allot of stories with people using the wrong fluid in the 6spd causing "other" failures.

I AutoX my MR and have off and on for 3 yrs, I use the Mopar Racing 75/85 synthetic as I have since the car had 10K on it. 42K now. I change it OFTEN, and I often get made fun of at my tuners shop because the fluid is always clean when we change it. I see it as preventive maintenance, ESPECIALLY on the 6spd.

I go 5-10K Max on the gear oils, and change them once a month if im autoX ing.

I also have seen at the track many 6spd owners using the "beatrush" undertray that does not have any cooling going towards the tranny. If you look on the OEM peice, it directs air right to the tranny fins. For the 6 spd this is CRUCIAL. So I still stick with the OEM undertray, or do not run one at all. On an Auto X course you dont get up to the speeds to where the undertray is evective at downforce anyway.

I have seen some pretty high HP and TQ Evo MR's out there that Drag race often without anything like this happening. My gutt feeling on this, Defective piece. Must have had a hair line crack in the slider from the factory.

Good Luck really, that looks very exspensive. My broke *** couldn't afford to fix something like that. Wow.

 

^ seems to look like a defective piece.. the break is very very clean

something like that isnt supposed to happen during a slow shift

 

I used to change all oils on the car every 5-7Kmiles, depending on use.. and that includes all gear oils and both diff oils (I have AYC)... I used fully synthetic Motul oils, 300V line... so the oil was ok..
My gut feeling is that overheating of the tranny on the track did not help things, but looks like defective part.. or maybe some damage from the first owner (I bought the car at 5000 miles..)

the repair will be less than thought.. if it was all new, the car would be a writeoff.. I bought two 6 spd boxes (with damaged cases), low mileage transfer box and AYC diff for approx 2200 USD + 1000 in shipping, customs and taxes.. I am doing all the work myself... so there goes my FP Green HTA budget..

 

yeah, it did not happen during the shift, but only after the car came back on boost..

Ill get some more pics..

 

Wtffff.

 

ouchhhhh man!! that looks crazy lol

 

Needs some superglue and a polish and it's ready to go.

 

Omg

 

damn dude that tranny is toast bud, sorry
I wanted to go with 6 speed conversion, but now i think i will stay with my 5 speed.

going to go with sheps soon i think, 4th starting to grind.

 

You'll need some of this....



and one of these to fix that...
