problem

[Kingsford G]

Car goes and drives but when u try putting your foot down it revs to 5 tousand and doesnt do anything I have no lights flashing on the dash

So it goes when you speed up gently but when you floor it just revs and no acceleration?

How many miles has it done?i bet it is lower than 130k..

Yes

113k

113k

Oh dear. Get the fluid changed and flush it first but once they start slipping it's terminal only good thing for you it's a 3 speed so a really common box to find.

Had the fluid changed abt 6k miles ago

Sounds like the box / torque converter is on the way out

As cleymore suggest could it be the torque converter

[abdul]

Would a box from a v70 t5 be the same as a v70 r

[jamesy12345]

3-speed? 4-speed AW42 I think it will be

[abdul]

3 speed auto

[jamesy12345]

3 speed auto

never heard of one

I think it's the same box in a T5. The non-T5s will probably fit also but have different final drives

[abdul]

Sorry I think its the 4 speed auto

[jamesy12345]

Sorry I think its the 4 speed auto

I've got the same one in my S70 T5. I've also got another AW42 auto box from a 2.0 litre to go in it at some point - AFAIK they are all the same box but like I said with different final drives. R and T5 final drive are the same

Do a stall test to check the torque converter.........put in bottom gear with the handbrake and footbrake on and go WOT the revs should only rise to about 2500 and then stall the engine.......only do it once or twice in succession as the oil may overheat!

Also not sure but an auto 3 or 4 speed box usually has an overdrive and needs a relay for it to go in .......maybe the relay has gone kaput so it stays in 3rd at 5000 revs.!!!

As andysr suggested tried the car in lower gear l it holds the revs near 2k doesnt shoot higher was playingwith the gear shiffting them from p to l back and forward car seems to be better going to give Iit a flush and see how it goes seems to be a lot better

[Kingsford G]

It is an Asin 42/50 box,you might have the sludge on the torque converter teeth from poor maintenace making it slip so drain the fluid from the sump and see if you find any metal dust or particules in the fluid and refill with the same amount and do it the same thing every 50-100 miles,its called a stage fluid change which is a gentle way of flushing rather than shifting all the crap in one go that may result in g/box replacement.

Going to do a flush which is a good place to buy the oil

If you're just doing a flush then get the cheapest that you can find. I'm doing the same to my two V70Rs - just bought 25L of carlube dexron III for £65 which I'll use to flush them out, then I'll get some decent stuff in a few 1000 miles and flush the cheapo stuff out with that.

Re the sources, I have a trade account with MotorWorld which is where I've got the cheapo stuff from. I'll be using AMSOIL as the 'proper' ATF later on - its rather expensive... I paid over £120 for the stuff when I did my old 850R a few years ago.

That's promising, get a flush changed and on the final flush use the best oil you can, 70 series cars with the AW42's are recommended to have Dextron III oil

Unfortunately the direct engagement of the torque converter, the overdrive function if you will, is controlled by the ecu not a relay like earlier cars.

Euro car parts,get Dextron III as mentioned above.
