Tim,

Ask the seller to confirm that it's in full working order before you part with your money.

Please ensure the Turbo 1.8 fits, it is listed at £800 extra over the 1.8 Auto box.
Give Rimmers a ring or XPart direct.

Yes you are right John the numbers are different and it looks like it will be risky buying this one now


Unless someone knows any different and as actually swapped one over before, very slim chance i know!

If i can't find a replacement box soon then the car will sold or broken for as much as i can get as all this messing around is getting me down

Guys, stay cool.
John is wise to urge caution with a project like this. However, retail prices have no bearing on technical matters. The £800 excess is probably down to supply and demand.
Secondly, part numbers are also irrelevant. The same product is often sold under different Rover Group part numbers.

I told you it would!
It will be less stressful to repair your existing transmission; please believe me, I've been there! You haven't said what exactly is wrong with it. Can Club members help you diagnose the exact problem? Chances are you will not need the whole lot reconditioning. When my wife's Metro's automatic gearbox went bang (literally) I was quoted £1,500 to rebuild it. I fixed it myself for £300. Tell us what's wrong and we'll try to help.

Hi Simon

The gearbox has already been looked at by The Wimbledon Automatic Gearbox company who could not find confirm what was wrong and why it
will sometimes find reverse gear and that also occasionally loses the higher gears.

They went on to say they had not seen one acting like this as yet

They also could only offer me a strip down to try and find the fault which would so they told me most likely find either a broken solenoid or the clutch plates have come apart which would mean a complete overhaul.

Either case prices were from £600 + VAT to £1800 + VAT.
So I decided to ask around on this forum for help and was directed to Corin who has changed the fluids twice and swapped ECU unit and we still have the same problem showing.

This diagnose cost me £76 and didn't really tell me anything I already knew


So the most economical (only economical) for me is to look for a secondhand box and have that fitted as other solutions could have me spending money without finding the fault as these gearboxes are very complex.

If you know (or any one else does know) of a specialist gearbox engineer that can look at mine and give a definate answer on what the problem is then I'm all ears!

Tim

I agree that your fault is highly likely to be electrical; probably a solenoid. According to the manual these are accessed by removing the oil pan. Neither the engine nor the transmission needs to be removed from the car. One club member has done such a repair (Marconi). The MG Rover manual says that 5th. gear is lost when solenoids fail.

... or the clutch plates have come apart ...

I think this is highly unlikely unless your transmission has been severely abused. Hydraulics are incredibly reliable. They sometimes leak and brake band linings can wear out, but only in the long term. Low fluid level also produces temporary fault symptoms, but I'm sure that Corin is aware of the quoted temperature range when checking ATF level. Has the selector lever cable adjustment been checked?

If you know (or any one else does know) of a specialist gearbox engineer that can look at mine and give a definate answer on what the problem is then I'm all ears!

Give Ashcroft Transmissions a ring. They're in Luton, which isn't so far from you I imagine. I hear that they know the Jatco box well and have the service tools (01582 496040)
ashcroft-transmissions.co.uk

Also talk to JP Automatic Transmissions in Bristol (01934 852772). They re-line brake bands and rebuild torque converters in-house so know their stuff! They're also very willing to discuss customers' problems on the 'phone. Don't be put off by their location. If they can help, it will be worth it.
jpat.co.uk

I'd be interested to hear what these companies say.

Edit: I've just reviewed the history in your previous thread (EP Mode and now lost reverse gear) and see that reverse gear comes and goes. This is not going to be a mechanical failure; it's going to be computer silliness or a faulty sensor or solenoid. But you're right to wonder who on earth can help. In addition to Ashcroft and JPat, there are some forum members who run businesses specialising in 75/ZT repairs; Lates and EMS (?) come to mind initially. They may be able to point you in the right direction.

Hi again Simon

One club member has done such a repair (Marconi)

I will have to ask Marconi if he would like to help me then

I think this is highly unlikely unless your transmission has been severely abused. Hydraulics are incredibly reliable.

Low fluid level also produces temporary fault symptoms, but I'm sure that Corin is aware of the quoted temperature range when checking ATF level. Has the selector lever cable adjustment been checked?

I will have to ask Corin about the Cable adjustment just to make sure
but know the fluid has been done aswell as EAT ECU swapped which made no difference

Give Ashcroft Transmissions a ring. They're in Luton, which isn't so far from you I imagine. I hear that they know the Jatco box well and have the service tools (01582 496040)
ashcroft-transmissions.co.uk

I called them and was told they deal with Land Rover gearboxes only
but the receptionist took my name and a n engineeer may call me back

Also talk to JP Automatic Transmissions in Bristol (01934 852772). They re-line brake bands and rebuild torque converters in-house so know their stuff! They're also very willing to discuss customers' problems on the 'phone. Don't be put off by their location. If they can help, it will be worth it.
jpat.co.uk

I called them up too but engineers were busy so sent a detailed email as advised by receptionist and hopefully someone will advise me

It is a problem knowing especially shop/dealer wise who you can go to and trust.


I would obviously try the forum member dealers on here you mention
and would have already if they were closer to me

Will update later if i get any news

Tim

I've now had replies from both Ashcroft's and JP Autotransmissions
and its suspected from Ashcrofts that i have an internal clutch problem
and that the large band that goes around inside is probably breaking up ?

They also say it's unlikely to be a solenoid issue as wouldn't normally get the symptoms i have.

JP transmissions Bruce sent back a email to me also possibly pointing to the known cracked piston problem which can cause the loss of reverse gear

Must say both compainies replies were fast and first class so highly recommended and friendly companies to deal with as Simon suggested


Unfortunately looks like I'm still stuck with either finding a good secondhand box soon (in the next week or so!) or breaking my car up as spares.

I will PM Marconi for other suggestions just incase


will update as it goes

Gasp! So I couldn't have been more wrong then!

At least you've got a couple of diagnoses at last. I'd better not say any more.
