reggie Posted December 5, 2008 Share Posted December 5, 2008 The auto box That I have just fitted seems to have failed after only 40-50 miles. It was fitted, filled up with oil, tested around the streets then I drove it home down the motorway for around 35 miles back home. A couple of days later I drove it up & down the village then parked it up for a few more days. Then yesterday morning I started off on my journey & as I pulled off 1st gear seemed to stick in gear for too long then changed with a jolt, A mile or two later I completely lost all drive with no forward or reverse gears.

Pete Attryde Posted December 5, 2008 Share Posted December 5, 2008 I would read this if you haven't already as it has lot's of useful info on diagnoseing (sp) a failed autobox. Unfortunately when mine lost all drive I needed a new box. Pete. Quote Link to comment Share on other sites More sharing options...
paintman Posted December 5, 2008 Share Posted December 5, 2008 Transfer box hasn't jumped out of gear? Quote Link to comment Share on other sites More sharing options...
reggie Posted December 6, 2008 Author Share Posted December 6, 2008 Thanks Raceface for the link, I've had a look & tried a few things. I've tried it in park etc & checked that it didn't jump out of gear in the transfer box. I've also checked the oil pressure on the box & there isn't any After a few emails to Dave Ashcroft he says that its the oil pump in the box that's gone. Is that what happened to yours?

Pete Attryde Posted December 6, 2008 Share Posted December 6, 2008 According to Ian Ashcroft there is a three legged drive member within the box that can/does fail and leads to a complete loss of drive. Mine still had oil pressure. Pete. Quote Link to comment Share on other sites More sharing options...
orangemach5 Posted December 6, 2008 Share Posted December 6, 2008 Did you make sure that the torque converter was definatly all the way home into the pump, its quite common to bolt the box up, start the engine and the converter just rips the pump drive to pieces when its not located properly.

paintman Posted December 6, 2008 Share Posted December 6, 2008 A look through http://www.ashcroft-transmissions.co.uk site in the autobox section gives you the correct fitting heights for the TC. Measure from a straightedge laid across the bellhousing to any of the four lugs on top of the TC. Neead to be careful that it doesn't slide forward when refitting the box. And as said, if its not on right it splits the pump. Quote Link to comment Share on other sites More sharing options...
reggie Posted December 6, 2008 Author Share Posted December 6, 2008 I didn't actually fit the box myself, it was a mate who did it in on his own. I have obviously asked him if he did it right as I know as well as he does that incorrect fitting can cause oil pump failure. He has assured me that he located the torque converter properly when he fitted it & can't understand why this has happened, I even drove it home 35 miles that night with no problems. So its a bit of a mystery, I've been wondering if maybe the new filter & oil change has caused carp to block the filter but I can't imagine it would have blocked so much to cause complete failure. The box was in my mates rangie for a couple of months while he drove it around & he said it as fine, so you would expect it to be still ok.

paintman Posted December 8, 2008 Share Posted December 8, 2008 Manual does give one symptom as 'intermittent drive & high pitched squealing noise'. Suggests problem is blocked filter or low fluid level. Quote Link to comment Share on other sites More sharing options...

Suggests problem is blocked filter or low fluid level. I've thought about taking out the filter & replacing it again just in case it has got blocked.

reggie Posted January 2, 2009 Author Share Posted January 2, 2009 Sorted the gearbox now, had to fit another one in the end. The first one had been fitted incorrectly by a friend of mine & crushed the oil pump as the torque converter wasn't on right Quote Link to comment Share on other sites More sharing options...
