Good evening, new poster here, been lurking for a while and have gained invaluable knowledge from those posting with similar issues, so a belated thnk you from a pensioner who drives these lovely motors but has less hair an less in the pension pot because of the thing :)

I've had an issue today that shown up as transfail PR03. Had my mate clear all faults on the diagnostics. Sorry didn't write the codes down.

The symptoms are as follows.

Set off this morning and give it some welly,heard a whining noise (similar to a belt slipping) Drove about 20 miles and got a vibration through he steering wheel (thought I had a wheel balance prob) Pulling away from roundabout and no gear engaged and then a sudden jerk into gear. Que warning on dash Tansfail PR03. Then the warning goes off.

It seems like the car is okay until it gets too hot and then plays up.

Had a similar issue last week the car got hot and wouldn't go above 3rd gear.

Had filters, trans fluid,radiator and cooler box all cleaned 5k ago.

Any help, pointers for my friendly local mechanic would gratefully received.

Thanks.

You have the ZF 5HP24 transmission and it sounds like you may have multiple issues. First, though, you should check the transmission fluid level.



Only use Mobil ATF LT71141 fluid to top-up your transmission, seeing as you're in the UK.

If the transmission is refusing to upshift into the higher gears, in all likelihood this is caused by the transmission fluid overheating. This is usually a result of restricted flow through the radiator or oil cooler, due to age. There are hundreds of threads on here covering that particular issue.

This wouldn’t cause the TRANS FAILSAFE PROG error though, which is more serious. The reason for failsafe being flagged will be stored in the controller and the error codes are a fundamental part of the diagnosis – you need these. I suggest you make a note of them next time it happens, otherwise we’re just guessing.

Phil

Hi Phil,

Thank you for your reply. I'll obtain the codes next time I'm at the garage.

One again, thanks for coming back to me.

Hi Phil,

I read your comment on a previous thread regarding the use of the gearbox on these cars. Mine does less than 5k per annum and is all urban driving so very rarely gets into top gear. So I am assuming that the clutches on the lower gears are shot, especially when the oil gets hot. Great observation on your part.

I will get the codes from the diagnostics to see if it is anything else. I really like this car and bought it as my last car ever :)

How much for a re-built? In your expert opinion.

err 1953 l322 mk2? the l322 is the MarkIII and was not produced until 2002 for the european market.

The MarkII was the P38. introduced 1995 and sold beside the "Classic" Range Rover soft dash models

Hi,

The codes showing up on the diagnostics are

P0730 Incorrect gear ratio
P0732 Gear 2 incorrect gear ratio

No other fault codes come up.

The car drove ok this morning. I assume that is because the oil was cold.

TIA for your expert advice.

A ballpark figure for a re-manufactured transmission, including removal and reinstallation, would be around £2000-£2500 incl. VAT. If someone’s offering to do it for less than £2000 then they’re cutting corners somewhere.

Just as a reference, I charge £1375 +VAT for a re-manufactured 5HP24. This includes a re-manufactured torque converter, all genuine ZF parts used throughout, a genuine IBS Filtran filter and 11 litres of Mobil ATF LT71141 fluid. However, I’m 200 miles away from you and I only work on transmissions, not on vehicles.







Your error codes indicate that the turbine and output speed sensors are measuring clutch slip in second gear. This is not a good sign, unless it’s just down to low fluid level. However, low fluid level usually gives problems when the transmission is cold. If the transmission is fine when cold but then develops problems once it has warmed up, then this could indicate an internal hydraulic leak in a clutch circuit.

Hi Phil,

Thanks for the reply and the quotation for a rebuilt. There is a LR specialist locally so I'll give them a call today. The car is booked into my mates shop for Monday. I'm going to ask him to flush the rad and cooler box and check fluid level, but I think I'm clutching straws.

Thanks for your time you spent n this. Much appreciated.

Hi Phil,

Sorry to be PITA. The only unanswered question now is the vibration through the steering. Would this be associated with the tranny or is it a separate issue?
And one more. How much to ship rebuilt to the smoke
Thanks

I’ve not heard of a transmission issue causing a steering vibration before. The only vibration commonly associated with the 5HP24 is due to wear in the torque converter lock-up clutch which creates a noise/vibration not unlike driving over a cattle grid. This is commonly felt at around 30mph when travelling up a slight incline.

A Range Rover 5HP24, with fluid, weighs around 95kg so the shipping cost, strapped to a pallet, is typically around £70.

Phil

P.S. As the coolant feed to the transmission oil cooler comes from the bottom eight rows of the radiator, all of which are below the level of the bottom hose, flushing the main radiator unfortunately does not clear out the sediment that is responsible for the blockage. Radiator replacement is the only fix. A brand new OEM (Behr/Hella) radiator costs around £160.
