1996 auto kzn185 not getting over drive???

[surfee]

hi there.

does anyone know why my truck is not getting O/D

[likemagic]

one thing to check is the auto has a temperature sensor that will not allow over drive before it has warmed up.

Check the overdrive off light bulb hasn't blown and you have got it switched off

wen im at 100kph i flick it on and off light works and everything but the revs move like 200rpm then go back im doing like 2700rpm at 100kph with 285/65/16s

found this great site http://www.toyotaguru.info has step by step instructions on stripping and rebuilding A340E and A340F auto.

Also found this http://www.yotatech.com/f116/a340f-rebuild-254032/ on someone that had a go.

and a fault finding guidehttp://home.wjw.co.nz/Toyota/A340/autotrans.html

When was the last time you done a service on the auto? Fresh fluid does wonders for autos

the last service it got was last weekend and still no good
