Stag auto gearbox problems

[Peter Carr]

Hi, Can anyone give me any advice on my Stag type 35 auto box? It has a bad clung when I go from drive to reverse and again when I select drive again. Also it seems to take a long time to get into top gear and when I select park it does't lock into position all the time, you can push the car forward and hear it trying to locate. I have had the car up on axle stands and noticed a bit of play in the diff. I have only recently bought the car and noticed over the last 4 yrs the only millage the car has done is when it has gone for its MOT. I did think of changing the transmission fluid and filter, but was advised against it. Can anyone help. Thanks Peter

i would start with checking the selector adjustment  seems the gate slots are all misplaced to where the box thinks it is.

and the kick down cable setting , this has a small ferule crimped on the  inner cable and at idle this must be close to/ 0.5mm from the cable abutement at the carb end .

changing the oil and drop the filter /sump is not any real problem ...more messy   ATF gets everywhere

Clunk when engaging drive, reverse or especially switching between drive and reverse is usually the result of backlash in the drive train rather than a gearbox issue. Diff, prop-shaft joints, driveshaft joints or splines are all possible sources and sometimes, on a well worn car you can hear a chain of clunks working back down the car.

High idle speed can increase the violence of the clunk.

other issues sound fluid/filter related. Not sure why advise you not to change it...........

Park issue is potentially the most awkward though external linkage adjustment should be checked before getting too worried.
