Hey guys

Ill start by saying I've searched and just can't get exact answers.

I recently bought another xr6t bf with the ZF box snswers can't be happier, but having never driven the zf before I'm unsure what's normal and not. It's got 170,000km and I'm planning on doing service very soon.

The issue I'm having is the gear changes. If I'm cruising at say 40km and give it a little squirt then back off it will linger in that gear for few seconds bout 2000 revs before changing gears. I've spoken to few guys bout this and can't get clear cut answer if it's the way the stock ZF performs, whether it needs oil change or it's not a good sign.

Any help to clear my nerves is hugely appreciated

Cheers

Az

Pretty sure its normal as the gearbox is expecting you to continue running that gear out from your little squirt, so it holds the gear for a bit and then thinks your soft for not keeping your foot up it and decides to hook the next gear.

Yea they are very smart boxes. They try to learn your driving style and all.

Still get it serviced though.

Yeah it's intentional, they called the feature 'gear hold on lift-off' or something. Essentially based on the theory that if you're giving a bit of stick then suddenly lift-off the accelerator pedal you'd be going for the brake...so to change up a gear wouldn't be ideal.

It's a very intuitive box that people either absolutely love or despise.

Holding gear, after taking your foot off the accelerator abruptly while giving it a boot full is normal.

It will ususally do it more while in sport mode, but a gentle press on the accelrator will usually make the the box slect a higher gear, then it will drive normally.

I think it holds gear not only for braking, but for better response, as in if you're taking a bend it will hold gear in anticipation of braking, and also in anticipation that you will be accelerating out of the corner...
