Mk1 Auto

Hello All,

I have an old Mk1 automatic that I'm trying to get the last few miles out of before I have to find a replacement. I'm pretty sure I've lost 2nd gear but I'm more interested by the problem I'm having with 4th gear.

Over the last 5000 miles 4th gear has become more and more reluctant to engage. It would not engage until higher and higher speed was attained to the point now when it does not engage except under the following conditions: during the first couple of miles of a journey; after 40 odd miles when it will occasionally engage at 50 mph and above; when driving up a slope.

The car is not worth any gearbox rebuild but it does deserve - for excellent service - some remedial care before I give up on it. I have changed the vehicle speed sensor and the transmission fluid without any improvement.

I'm intrigued by the 4th gear problem and would like to understanding what is going on in case I've missed something obvious like another miss-behaving sensor.

Your comments would be much appreciated.

do NOT overfill the thing. Keep it up tot eh mark, but not past it. Transmission fluid is picky, and may not appreciate being overfilled the way it is. Check it on a levle surface when hot.
