Hi. Thank you for the forum. I recently bought my van. I have a transmission issue. Had a slight leak at the accordion looking dust cover and at the slave cylinder and also at the front near the oil pan. I went to have the fluids changed. I was told the recommended tranny oil was MT 90. So they drained and filled back up. The old oil was pretty bad. Its now leaking really bad at same spots, and shifting into first gear the van violently shakes as I let out clutch. It's getting worse and starting the shake as I shift into 2nd as well. Could this be because the new fluid put in?
