think my zeds made its intentions clear today, took it to ssr to see what it was running like,

 

coming off the M25 i noticed my auto box stopped working properly, will not shift higher then 2ed + o/d, thinking it was a couple of mile to SSr id look at it there well,

 

and about 1/2 mile before i got there it emptied its radiator, through a meter matrix hose....

 

fixed it, and filled it back up with water

 

dyno showed good AFR, same boost but less power....??? baring in mind its got less weight on the crank and japspeed elbows, and bigger turbos, it cant be good.

 

to cut a long story short it made it home, but its running hotter then normal, and the gearbox is fubared.

 

 

anyone have any idea what could be wrong with the auto box?

 

i think its running hot because its was having to be revved to get it home.

Sad news hope someone can help mate.

now im really confused.....

 

when i got it home i disconnected the battery to reset the both ecu, and now its driving and changing like normal again??? with no fault codes what so ever???

 

is there a safety mode on the auto box?

would say clutch plates are Heating the oil up ... then starts slipping ... putting more load on the engine

 

are you using the Auto oil cooler in the stock rad ?

 

Manual conversion then ...

long since fitted an additional cooler, also a lrg alloy rad, and nismo thermostat.

 

if it was a manual id say its clutch was slipping, but it wont go into 3ed or 4th either...changing from 1st to 2nd was very violent too. but now drives normal again???

 

the cooler felt hot as it normally does.

 

 

it went on the dyno with the box playing up so that could be where the power went....

when was last time oil was changed in the box ?

tbh i dont know.

 

do you think it could have broken down with the heat?

its poss ...

 

its the first thing to try

i'll do that tomorrow then, what fluid do people recommend? its a 7.7Lt system on an import i think. but 5 should be enough for a change right?

eerrmm not sure on the amount or type

Dextron 2 about 4 litres should do,you won't get it all out of the convertor.............

went to take it for a drive today, and its gone again, no fault codes on either ecu or auto ecu, so i assume its mechanical, i've changed the fluid but only got about 3l out of it, so ill try to do it again tomorrow to get even more of the old fluid out,

 

worrying thing is the fluid looked like engine oil and had the consistency of water... :(.. dread to think how long its been in there.

hi black auto oil isnt a good sign ....so box is problely fooked....
