Meriva B automatic transmission

[John Womack]

Hi my 1.7 diesel automatic sometimes jerks  forward or jerks when downshifting (ie slowing down for lights etc). It's a 62 plate with 88000 miles, would this be resolved by changing transmission fluid or is it likely to be more involved than that? And is changing fluid easy, like an oil change? Cheers!

Hi John, what speed gearbox do you have? Apparently if its the 6 speed gearbox, then it can be quite tricky to do. But I have the 4 speed auto in my 52 astra 1.6, and I have changed the oil very easily. There is a drain plug right on the bottom of the box, and mine took about 4 litres of oil poured slowly with a funnel down the gearbox dipstick tube. 

Mine was a bit jerky when i bought it, and it turned out that previous owner had a local garage change it, but put ordinary gear oil, not ATF in. Once I had drained and flushed , it is now a lot smoother.

Hope this helps.

Regards AndyR.

Thanks Andy, I'm not sure and don't know how I'll find out. Think I may ask a local garage but ask if they deal with auto transmissions first!
