Galaxy Tdi Auto Gearbox

[richardman101]

i have a 1999 galaxy ghia tdi auto, with a slight gearbox issue. i dont know whether its electrical or mechanical or if it needs an oil change so any help and advice from anyone who has had similar problem or has knowledge would be very very much appreciated! the gearbox goes into gears fine, it drives fine and changes up and down as it should, however when travelling at fixed speed of anything under around 70mph the revs 'surge' a little approx every 5 seconds. it sounds like a 'slip'. when i say surge, i mean there is a slight increase in rpm, approx 300rpm then revs drop back to constant again. quite a strange one for me - i have driven many autos before, some of which had faults but none which have done this!! i dont want to keep driving and get a hefty bill for a replacement box! help please!!!

Hi there

First thing is this the 4 or 5 speed changing fluid and filter on 4 speed is easy as sump can be removed and filter changed, on the 5 speed you cannot change filter without G/box removal, on both boxes you will not be able to remove all the fluid because of design so to do a good change you need to change fluid 2 or 3 times with a drive between changes the colour of the fluid is a good indication as to the condition of the fluid it should be a cherry red colour.

This is all against what Fords say the fluid is in there for life.

 

I take that to mean 300rpm rise with no increase in speed

 

Have you had the car long or just bought it with this fault

 

I think I would be inclined to do a fluid level check first you will also see the colour of fluid also.

 

There is a set procedure for checking fluid level/draining in the FAQ section

Hope thats of help to you ;)

hi chrispb - firstly thanks for replying to my post - much appreciated. i bought the car last november and it has had the fault the whole time, never getting any better or any worse. yes, correct, the revs increase but the speed doesnt. i did read the info on here regarding the procedure for checking the oil level, and have spoken to frauds who did say that the box is sealed for life, which seems a lame approach to me. i will attempt the oil level check this weekend but think it may be an idea to buy a replacement filler tube/dipstick thingy part first as i have read that people have had them snap off when removing to check, i assume this relates to my gearbox which is the ag4 type (4 speed), and the sump is accessible for removal. i wondered if removing the sump to change the oil may be a simpler option, at least for the first change if there are filters to change aswell so as to do it all at once. i have spoken to a couple of auto specialists today who both seem to think it could be either electrical or mechanical failure rather than an oil issue, however i have also heard that sludgy oil causes problems and i can hardly expect mine to be rosy red after doing 110k miles!! ;)

thanks again for the info. rich.

did you buy from a dealer?if so how long was/is the warranty?

hi gregers - unfortunately it was private purchase and i didnt notice the problem at the time - you have to be driving 'carefully' not heavily to reproduce the fault!!

Check the oil first.If the oil is brown or black in color then it deffo whats changing. If not then i dont think an oil change will make any diffence.Other than that you maybe looking for another gearbox,Just a word of warning tho,buying a secondhand box might cost you big time.I've got to the stage now where i wont fit secondhand box'es anymore as somtomes they can be worse than the one you take out!

thanks for the advice - i have just been to fords to order a replacement cap for the filler tube on the box so when that comes into stock and i have collected it, i will check out what my oil looks like! cheers.

Hope thats of help to you :rolleyes:

hi again - i have read that oil must be ford-specific. is this correct do you know, or can i use dex-3 or dex-2 universal stuff for my oil change if i do one? after all, the properties of new oil surely will outweigh those of brown sludgy stuff if thats what i am running on atm!! thanks again in advance for any advice!

It would seem you do need Ford fluid but im sure you can goto any motor factor/shop and get somthing cheaper that meets fords spec.Just look on the back of the bottle first. If your oil is brown then it will deffo need changing.Cheaper than looking for another gearbox!!!

Hi again I think I am right in saying the fluid for the AG4 is different from the AG5 mines the latter and I used Mercon V fully synthetic at
