is KEAS near u?hes the man to see

[pharoahs33]

i have no idea. never heard of the place. ill look it up

ive seen standard autos take 250kw with no problems.

ive also seen built ones take 300kw+ with a shift kit and a clutch rebuild.

someone on here has run 315odd kw on the auto, look up either 4doorsleeper or dangerman4.

both have high powered auto's and lots of info in their threads.

Yeah Keas in Melbourne is the right place but I would recommend you get a valve body upgrade from MV Automatics in Adelaide then get any old auto transmission place to put it in for you. Mike is head and shoulders above anyone else in Aus when it comes to Jatco trans.

Also I strongly recommend you get a trans fluid temp gauge in your car. It's well worth knowing what temp it's running at and would have saved me a full rebuild if I had one before I killed mine.

sic thanks. im only running 170kw on 11psi. so i need this car to pick up and go because its slugish between gears.

sorry also just wanted to know what temp is the tranny supposed to stay under to be safe?

Yeah it's dangerman4, his last dyno run was ~300rwkw which, also is believed to be the limit of the stock trans w/ upgraded valve body. Also, a complete rebuilt one from MV Automatics has seen around 500rwhp.

so what have u done exactly to your auto tranny to get it to take 300kw?

With Just the MV Valve body it can hold up to 270rwkw, its a really good idea to get a Trans Cooler also to keep it from heating up too much. But shifts really nice well worth the money.

yeah i have a pwr trans cooler already put on. i like the sound of the mv shift kits but id rather get someone here in melbourne to do it in the shop. so the mv valve body is basically a stage 2 shift kit? is a mild or heavy when the gears change?

[Abo Bob]

Try to generally keep it under 100C but can over to no more than 130 as long as you change the fluid not long after.

Abo Bob: Which/where transmission oil temp gauge have you got?

Also, what kind of installation are we talking?

It's just an engine oil temp gauge I got from Just Jap. I went to pirtek and made up a t-piece to put in line on the fluid to trans cooler line with the sender unit.

ill be installing one of those temp gauges in soon with the description Abo Bob gave me. ill post pics/prices when its all done.
