hi friends, hope you can help me here

68 matic, 33,400miles on the clock, engine sounds good.
penrite classic light oil changed 3months ago.

when cold (warmed for only 5minutes): gear changing is fine, quiet, smooth, Reverse engaging is also quiet

when warmer (warmed for 10+minutes): putting Neutral to R, N to Drive, or R to N, there is a loud CLONK and shock through the car.

is there a way to lessen this as i feel if it is done too much, wear and tear of the engine is promoted

thanks

Idle speed is too high. Should be 650 rpm in NEUTRAL for autos :wink:

According to Leyland shop manual.

Mine `used to be' a Morris MiniMatic. Still sez so on its rump. But it's had a 1310 S transplant, with lots of goodies... :P
