Hi all
I have a 2004 voyager 2.8crd. gearbox has started playing up but only seems to happen when warm. From cold changes nice and smooth but as soon as warms up it seems like the box is slipping. (similar to a manual clutch slip) If you rev the engine it will engage again but soon after starts to slip. Anyone any ideas please.
Thanks
Mark

 

When was the gearbox oil last changed?

 

To add to that ...ALSO REPLACE THE TRANS. FILTER

 

If you are due a change, get a new pan as well at the same time, they can warp when taking them off, so better to have a new one just in case. If you search on here, I can't remember where it is now but there is a model number for a new pan that comes with a drain plug on it.

 

Thanks all for the replies. have changed the oil and filter and seemed 80% better. it still seems to slip when up to temperature but if you put your foot down it kicks back in and drives again. when it drives between cold and full temperature it drives really well. its as though something is breaking down once warm. Any ideas.

 

Not real familiar with the Diesel models, as they were not avail. in the USA. BUT per chance are you operating the van with the CEL/MIL illuminated on the dash?

 

Hi. The check engine light was on but the symptoms were still the same regardless of it on or off. It's very odd. Like I say when it runs under temp it is faultless which leads me to think that mechanically the box is good. Have had it to 100mph before it hits temp with no symptoms. I'm going to change the shift solenoid tomorrow as I've read that this can cause strange things to happen.

 

What oil did you use?

 

It would serve you well to have the van's computer scanned to see the code that the computer kicks the CEL on for, at worst it will HELP with diagnosing the problem. Rather than "flying blind" and replacing parts in hopes.
I recently had a trans issue with my 3.8 petrol 04 T&C that would kick in and out of the overdrive, NO CEL when warm and van weighted down, Turned out to be a worn throttle position sensor on the motor's throttle body. You COULD have something similar going on, as you haven't posted of pertinent info of mileage or previous maint. or how long this has been going on.
