Well hippo done as you said and theres still a wineing noise, wandering if its the wrong oil? any ideas?
How low was the auto oil when you were running it low on oil? How much more did you put it to get the level correct?
Personally I would only ever put the correct oil in, which is sold by main dealers. That's my personal preference. I know and accept others on here have used different oils which we've discussed on here in the past, but when asking the manufacturers to commit to this they will by email, but won't put it on their web site in the spec. Having had to replace my auto with a recon which cost £2200 fitted, the cost of the dealer oil to do a few changes is less than 5%. Even though mines on a low mileage it would be daft to change the auto if it failed again, bearing in mind v6 fuel costs and it's age. A sad thought I know but it's a reality.
Your auto won't like running low on auto oil. I guess it will stop the stuff inside being lubricated correctly, depending how low it was. Also may not have enough oil to keep the hydraulics operating correctly. If you run the torque convertor low on oil then it cavitates. That's when you get air in it and it gets damaged. The dealer told me after I run mine low on auto oil. Rotten sods didn't tell me it had a leak until I returned to tell them the gear shift went with a heavy bang again, 2 weeks later. Cost me a recon auto that did.
I'm guessing a bit here as I'm not an expert on auto's. I gained bit of knowledge the hard way. If replacing the auto oil and running it low on oil is the only thing you did, then it's likely this is the causes of the problem. Check around to see you haven't knocked anything which could be causing the noise. Low oil isn't good. It will cause wear which can't be put right without it being taken apart. As far as I see it you need a second opinion from an auto transmission specialist. Given that opinion you can make the choice to either drive as normal and wait to see if it gets worse, let them fix it if there's a problem, or just replace the auto. I guess it's down to their experience and diagnosis. Problem is they won't know for sure what the fault is until it's taken apart, unless they've done one similar before and can advise the problem.
My first suggestion is to contact someone like ashcroft transmissions who recon the jatco auto which is what you have. They will be able to assist from direct experience of these auto's. They recon them so they will have seen the possible damage inside too, and the effects of low oil.
