In warmer weather while driving I noticed that when starting off 1st, 2nd, and 3rd were selected normally. After 3rd the change to 4th was almost immediate and then 5th was engaged normally.
In cold weather (-1 and less) when setting off 1st engaged normally but when changing to 2nd it was as if the car was almost going to stop. Same when she was changing from 2nd to 3rd. Almost as if the brakes were being applied. 4th was attained normally then 5th also. However in 5th gear it would take a couple of miles for the revs to drop down to their normal level.
My thoughts are that she is low on oil which would be a surprise as it is a sealed unit and about 10,000 miles ago I had the oil changed in the gearbox. No sign of any leaks.
Today I was going out on a "lock down lets find something to do to the car" couple of hours. I had bought a large syringe come turkey baster thing so decided to suck out some of the power steering fluid and replace with new with the plan being to do that regularly until it all looks new. That was job done, no problem.
While attempting the above I remembered that there is a filling hole on the gearbox with a rubber plug so that the box can be topped up. Will this turkey baster I have fit into that hole? Yes it will. But, the rubber plug is missing. When I put the plastic pipe of the baster into the hole as far as it would go I tried to suck some fluid out but there was nothing there.
So the question is, and probably Joe.com is best for this,
1, How to tell how much oil should be in the box without, draining and refilling to manufacturers specs, and although no sign of any oil having been blown out this hole would it be possible?
