Don’t worry about the video titles too much, I cannot confirm this but 37179 does seem to have kickdown to me judging by the way it’s downshifting and the thrash certainly was great! In fact I’m jealous you got a run this good on 86 because I haven’t managed any at all! Not to say there’ll be no videos, just that the runs won’t be nearly as good as this I quite like this bus, great video!
This is definitely not kickdown. I drove many Mk2 B7TLs across different First regions, and none of them had kickdown. This was by First specification. Although this B7TL does seem to of been reprogrammed to a different shift pattern than normal at some point in its life, it still definitely does not have kickdown. The higher than usual RPM when pulling away is due to the gearbox shift pattern being setup differently to what is normal, and the vehicle changing from 6th to 5th gear several times is a design flaw of the 6 speed Ecomat. They are notorious for "hunting" between 5th and 6th gear, as 6th gear is an extremely tall gear and if the bus is not revving high enough to accelerate then it will downshift to 5th where it can. They will do this over and over again until the bus is doing a high enough RPM in 6th to accelerate. The higher RPMs when on hills is also not kickdown, this is called "Topodyn", a feature introduced by ZF where in if the gearbox recognises that the bus is on a hill, it will either downshift to a more optimal gear or it will hold the current gear for longer for better power. Once the bus is over the hill and on the flat the gearbox will default back to its normal and usually most economical shift pattern. ie changing up a gear at lower RPM.

Are these ones D7E?
D7C 👍
@@cwcptravel6936 on right i thought they were Es because they were on 37 numbers when there is loads of 32 numbers left
@@fin57 B7TL's and older B7RLE's were built with the D7C engines.
@@fin57 Some D7C B7RLEs have 69*** fleet numbers instead of 66***. Doesn’t mean they’re D7Es...
@@cwcptravel6936 Yes. And B9TLs don’t have D7Es, they have D9K engines
