Dadowiz Member 19 Member For: 15y 4m 2d Posted 17/07/10 10:04 AM Share Posted 17/07/10 10:04 AM Hi all, I have searched the forum pretty extensively and I apologise if I missed something. My ZF Gearbox is not shifting up gears when I have planted the foot to overtake someone. Basically If I put my foot down the gearbox is holding the lower gear in high revs (around 4,000+) and wont shift up. I know the box is designed to keep the lower gear in case I need the power again, etc. BUT I have held it reving high around 8+ seconds and it still wont shift up. Obviously I have it in D mode and the only way to get it to shift up is to move it to Sport Shift Mode and do it manually.Has anyone had this problem and can offer a fix? The car is standard other than a upgraded air box and filter, 19" wheels. Thanks in advance for your help!! Link to comment Share on other sites More sharing options...

Use Tranamax Z fluid. Do not let Fraud near it unless under warranty. even thenDoes it hold until the top of 4th gear ? Link to comment Share on other sites More sharing options...
wiresquire Member 266 Member For: 19y 11m 19d Posted 17/07/10 12:31 PM Share Posted 17/07/10 12:31 PM Gear hold, fast-off throttle (Automatic modes)Upshifts are prevented when the throttle position sensor detects the driver has instigated a rapid lift off of the throttle pedal (fast off) and maintains the current gear until the driver tips-in (reapplies throttle pressure). It also helps prevents shift busyness in sporty driving and inhibits the ‘running away’ feeling when cresting hills.Source: BF Falcon II press releaseDid you hit the accelerator again?

In regards to applying the accelerator again, yes, I tried that. It is definately holding the gear. *not happy* Link to comment Share on other sites More sharing options...
ZAP No boost, no bottle, just my foot on the throttle!

The gearboxes can be a bit too smart sometimes Link to comment Share on other sites More sharing options...

Ever since I had my car tuned it has done it. I had it serviced, still the problem remains.I've given up on D and Performance mode and only drive it everywhere in tiptronic because I can make it shift properly.Really hope the Xcal3 zf tuning can get rid of it.I havent however tried disconnecting the battery...

Dadowiz Member 19 Member For: 15y 4m 2d Posted 23/07/10 05:01 AM Author Share Posted 23/07/10 05:01 AM Ok so I took the car to Ford and to a transmission specialist just to have a quick chat and Ford tell me that I would be crazy to service the ZF as it should never be opened.. They wanted between $80-$120 to have a look at it and then said that a fix would probably be in the region of a couple of thousand dollars. This is before they even know what the problem is!!I took it to a transmission shop and he said to hook it up to the system and test it will cost approx $80. He thinks it is going to be an electrical issue as the box is fully electronic. I told him I would get back to him.I stuck my head under the car and it appears there is a transmission fluid leak somewhere so I think the fluid level is low causing the box to do funny things. I am going to get the transmission specialist to service it (Approx $350) and find the leak ($??) and hopefully problem solved.Funny how things work. As soon as I found out I was getting a nice tax return my Ford starting having issue, my Pajero died, my Toshiba laptop decided (1 month out of warranty) to break and my 3 year old LCD TV has died!!that's life!!Anyone had any leaks on the ZF and know approx costs? I read about a couple where the wiring loom goes in, any ideas? Thanks!! Link to comment Share on other sites More sharing options...
