Maybe its the wrong fluid. I'd make sure fluid is absolutely correct first. Take it to AT specialist shop and have then drop the AT pan - maybe AT filter is clogged. Dropping the pan would also allow you to inspect for any metal or other debris on the bottom of the pan. The AT in the SC430 is a pretty strong unit - very few problems reported.

Q: I recently purchased a 2008 Chevy Equinox with 81,000 miles. It has the non-GM Aisin AF33 five-speed transmission. The owner's manual states to use only T-IV automatic transmission fluid. I pointed this out to the shop when I had the transmission fluid changed. However, they used a machine to flush out the used T-IV fluid and replaced it with Dexron VI fluid. They told me that using Dexron VI is not a problem but I read on several Internet blogs and forums that using Dexron VI can damage this transmission. I asked two Chevy dealers, an independent garage and another transmission shop and I'm getting conflicting information. I would appreciate it if you could get to the bottom of this.

A: Hey, if it's on the Internet it must be true, right? The T-IV automatic transmission fluid meets industry specification JWS3309. Here are several automatic transmission fluids that are listed as suitable for T-IV applications: Valvoline MaxLife Dex/Merc ATF, Mobil 1 Synthetic ATF, Castrol Trans-Max Synthetic ATF, Quaker State Ultimate Synthetic Multi-vehicle ATF, Pennzoil Multi-Vehicle Automatic Transmission Fluid — to name just a few. Mobil ATF 3309 is a JWS3309-spec transmission fluid engineered for this application.

Like you, I found conflicting information on Dexron VI compatibility with JWS3309-spec Type T-IV fluid. Part of the issue is Dexron VI's "backward compatibility," meaning it is suitable for transmissions using previous Dexron ATFs. Aisin specifically recommends against using Dexron III in the T-IV transmission.

Remember this: Transmission manufacturers do not manufacture or produce their own lubricants. Oil companies do. I believe we can trust the product information on specific lubricants and their compatibility with specific vehicle components. So as long as the fluid used to refill your transmission meets the JWS3309 specification — no worries.

 

I bought 3309 from Lubuniversal last year. I remember it being the cheapest.

You can try to disconnect the cooler lines and use the engine like this guy does


I don't think it's necessary to drop the pan - because if it's not sealed well, it'll leak later. I don't think they have the gasket in Europe. They'll use a sealant.

 

I disconnected the cooler lines and it was VERY VERY VERY easy

Finally, I give the car back to the seller

Indeed, after verification of the serial number, the car does not have 140 000km but probably more than 300 000km (185 000 miles). The last technical inspection in Belgium of the year 2010 already announced 250 000km (155 000 miles....).

 

Odometer Fraud!!!
glad you were able to return the car!
good luck on your search for another SC430

 

It's not Toy but an independant dealer.

Thanks for my new search !! (and for your answers)
