First time I have had to take issue Dandydandywarhol wrote:Ain't got an overdrive but I think I know what you're on about - the torque converter doesn't LOCKUP until the 'box oil/coolant temp is at a certain temp.nfn wrote:Not allowing overdrive to engage before the engine warms up a bit is a common design feature of Japanese automatics. The faster warm-up to operating temperature should reduce engine and transmission wear and increase fuel efficiency. In short, they all do that! But I don't know whether the transmission in later bongos retains this warm-up feature. Probably it's a useless feature: the automatic transmissions on old Volvos don't do this, and often go on for 250,000 miles or more without a rebuild.
but nfn is correct, 4th gear is O/D on these units 3rd is 1:1. When cold both 4th & lock up are inhibited with 4th being the 1st one to be de-inhibited. Certainly am sir!Keep the heid alacrity - you're missing your wee boat in this cold weather aren't you?
