Grand Voyager 2007 2.8 Crd Auto Exec Gearbox Ok?

[GavinG]

I just bought my first Chrysler. Very nice car, much smoother than Kia Sedona I had before, but, I have a few worries. The first is the gearbox. At 2000 rpm the car does 56mph which seems quite low gearing and makes me think it is not getting into top gear. Can anybody with the same Voyager tell me what speed their car does at 2000 rpm please so as to either put my mind at rest or make me burst into tears.

 Put it to the 3 position and see if it seems to kick down.

I just thought I'd check this tonight on my way home (2005 2.8CRD auto) and that sounds about right.

Remember these are very old style American slushy boxes, so they've not got a great gear ratio, but they do learn.

 

Mine was doing exactly what you said, around 2k rpm it was 50 and above. I didn't force it down to the 3 shift but I'd expect it to have dropped if I did that. I pushed it up to 70mph and it didn't push the revs too much over 2.5k rpm so looks the same as mine to me.

Disconnect the battery for a short time, clear the memory.

Reconnect and drive the car the way you normally do.

Shift the gears manually when it gets warm.

You should feel the changees.

This is interesting since this is the first auto that i've owned,and i've got a steep incline as i leave the house,my 1,6 tdci goes up it no problem in 1st gear, the 2.8 crd struggles in D ,it manages better if I use the L position.

The incline is roughly 10 metres high over 20 metres long (it's quite steep )

[frogland]

Is it safe to shift from to D to 3 or L whilst in motion or does the vehicle have to be at a standstill ?

Hi

Shifting to 3 is safe at speed it's a bit like using the kick down but using L I would advise from stationary as it uses 1st gear for a long time then shifts to second.

It's almost like a get you moving gear but not at speed.

[andyb2000]

I'd also be a little concerned that you're having to do that on the incline.

 

Normally the box should shift down and cope with it, L and 3 are generally used when you're towing or wanting to force engine braking, the box should automatically shift down fully to handle any hills.

[frogland]

Ok,that sort of confirms that my boost problem is still present: code P0235

[andyb2000]

Agreed, that sounds more likely in your case @@frogland

Swap to a different thread to keep the posts clean, I've looked over your previous posts and agree it appears to be related to your MAP/TC sensor.

2100kRPM gives me 62MPH.

 

.1. @ a steady 40+MPH on a 70MPH flat road you should be in 4th - floor it - should drop 2/3 pegs and you do a schumacher.

 

.2 @ a steady 70+MPH on a 70MPH flat road in 'cruise control' - cancel cruise and drop speed to 31MPH - re-enable your pre-set cruise - and you do a schumacher.

 

- "caveat emptor" - what happens ?

Hey @@GavinG what size tyres are fitted?

 

Mine were wrong when I got it, too low a profile - tyre bays!!!!!!!!!! On a previous Ford Galaxy, all 4 tyres were different, 3 wrong profile (aspect ratio, proportion of width giving height) - 60 instead of 65 - and 3 were rotating the wrong way. Awesome.
