Auto strength

[old fordnut]

How strong is the auto in XR8's?

[rootster]

which model?????

About that strong.
Theyre stronger than the B series auto's but doing line lockeys and burnouts etc. will kill one pretty quick. Maybe tell us your plans or why you need to know.

Very strong I've found.

Just wondering as when I do some mods I want to know how long it will last. Like getting a stally, changing other bits and pieces. I've owned this car for 4 years and havent done any static skids or anything. Give it some every now and again, but thats about it.

I dont baby mine but definatly dont thrash it and my auto is still in working order with no major repairs, only recently had to do a bit of freshining up but thats still after a few years of coping with the supercharger.

cheers chris

If you don't drive like an absolute fool and understand what a car can and can't handle, then the strength is not an issue.

I think everyone here knows my endeavours and what my box has copped. It's still in good condition, shifts well and quick and shows no signs of wear. That's after 60k behind a 347, a skid pan day and many runs down the 1/4 all without a cooler too.

People pay out a lot on the old BTR 4 speed but mine has been great.

[frd906]

yeh mine has lasted 302000 kms on driving and doing long trips, but ever since ive been driving it which is for the past 3 years ive been giving it a bit bout she still drives smooth as well and good skidys lol

I cant speak for the V8 auto's but I guess it will be the same as the 6s when I say 'fit a HD tranny cooler on' to preserve life of the trans.

[Stattic]

arent they the same? the 6 and the 8 i mean... i thought only the t3s had different autos

Its the same auto it orginally came out with and the car just clicked over to 97,000 so reasonably low kms which helps.

Cant seem to find the paper work but nothing major basically it got a look over to check its condition, had to get a solinoid replaced as the shifts started to became a bit sloppy but that fixed it, supposivly a common issue. I also had a firm but tolerable shift kit and quite a large trans cooler installed and it runs awesome!

Where's Stav when you need some constructive feedback on the strength of AU autos?!

The t series has the exact same auto, all that was done to it was the shift selector shaft was modified to lock first when in drive, the same as yours does when u put it in 1st, this was only done due to the shift buttons on the steering wheel.

The 6cyl and v8 box is basically the same, the 6cyl box has a lower pressure multiplier.

And both of these boxes are very good strong boxes.

[old fordnut]

Excellent. Looks Like I've got nothing to worry about

[Dauphin]

I was told that the T Series cars have softer clutch packs in their autos to deal with the ESS / manual shifting. Would that be of any relevance here?

[blackers10]

well my box was behind a 400hp turbo AU XR6 and it suffered at least 1 powercruise powerplay day... plus drag runs and general crazy driving by its previous owner...
i now have it and its purring along shifting hard as ever

it was rebuild by a shop in toowoomba prior to all this.. tuff as nails with a 2800 rpm stall

certainly helpful when its been toughened up. What did it cost to get done if you dont mind me asking?

[blackers10]

$3300 i believe including highstall and trans cooler

I guess thats about average considering the parts involved. I assumed that included removing & refitting into the car?

[blackers10]

shoot Hotrod a PM.. he was the one that got it done and knows the details..

[blueoval]

ah no problems, cheers

Keep good fluid up to it and high temps away from it and they will last approx 250 to 300k km. Everything that has moving parts wears out eventually, but if looked after (in terms of servicing), you should be able to flog it all day every day for a few hundred thousand km.

[Mr Hardware]

JC speaks the truth. this goes for the I6 transes too, they're the same basically.

ROFL, i thought the exact same thing whenI read this thread

As has been said get a decent size cooler and you should be fine. As long as you are not hammering the box it should last a while, if your nice to it I dare say your block will need upgrading before your box...

Never had any issues with the auto behind my stroker, I broke 1 box about 2 years ago (lost 2nd gear), but it was getting an absolute caining at the time..
