Hey Disco Web,

After an infuriating three weeks of trying to purchase parts from Ashcroft, Dave Ashcroft finally told me today he wasn't interested in working with me as a customer and would not supply any parts to me. I will save y'all the drama (you can read my review here) but basically I was trying to purchase the upgraded C1/C2 one way clutch, planetry gearset and “A” clutch off from a 4HP24 transmission Ashcroft uses in their stage 1 and 2 upgrade so I could have a local shop here in Wisconsin rebuild my 4HP22 transmission and warranty the work. I was trying to ask Dave some specific questions about the parts and whether he would recommend I just purchase the rebuild4HP22 directly from him and forgo the warranty. He was the only person I could talk to even when I called direct (I alway got "You have to talk to Dave") and he would only respond in 2-3 sentence emails every week or so. After three weeks of getting nowhere, I called him out on his terrible service and he replied he wouldn't supply me any parts.

So now that I am blacklisted from Ashcroft- I wanted to get this forum's opinion on experienced US (preferably midwest based) shops that have a lot of experience rebuilding these ZF transmissions and can add the upgraded 4HP24 parts during the rebuild. I have been calling around to shops here in Northeast Wisconsin and nobody seems to have ever worked on this specific ZF transmission model. They also are quoting me $4000+ for labor and parts. I would really like the torque converter and valve body rebuilt as well and it's hit or miss whether my local shops can do either.

There is nothing specifically wrong with my transmission, but after spending two years rebuilding my engine and upgrading the rest of my disco into a capable overlander, the transmission/transfer case is the only thing I have not touched (both have 140,000 miles on them). I think its logical to pull both and get them looked at. My transfer case is weeping quite a bit of oil so I plan to tackle that rebuild myself. However, I don't trust myself for the transmission rebuild. Thanks in advance!

I wish I could help you with a transmission shop - I don't know any good ones.
My WAG is that at 140kmi there's almost nothing to worry about with the transmission - in my experience, they start to fail around 300kmi mark (without any significant abuse prior to it).

I love what Ashcroft does generally, but the quality of their rebuilds is less than stellar. I had two Ashcroft-rebuilt LT230s, both seep oil noticeably; another one I've seen leaked oil through a wallowed-out hole for the intermediate shaft. It should have been sleeved during the rebuild - but wasn't.
Maybe it was the reason for Ashcroft starting to manufacture LT230s from scratch.

Lamorna Garage in Seattle rebuilds Land Rover transmissions and transfer cases. It won't be cheap and you will need patience, but the quality of work they do is top notch. If you call them up and describe your situation, I imagine the owner will generally echo Peter's assessment. Still, if you want the work done and are willing to pay (and wait) for it, they'll do it.

Thank you both for the replies. I know I need to rebuild my transfer case as it is leaking quite badly and when I went on my first test drive last summer after rebuilding me engine, nearly all the oil drained out afterwards. I was assuming both transfer case and transmission have similar life spans, but given my issues with Ashcroft I will likely only rebuild the transfer case for the time being and do the transmission at a later date. My thinking was along the lines of, "Ive already replace 90% of everything in the car and thrown thousands of dollars at it, whats the harm in spending another few grand". (If you can't tell, I am currently living in my moms basement and am terrible with money).

This is a good tip about Lamorna Garage, when the time comes, I will reach out to them for a winter project. Does Ashcroft have a US distributor for LT230 rebuild kits?

Falconworks here in Tucson? There's also Lots of transmission shops in Phoenix AZ. The ZF 4HP22 I think is also used in LOTS of BMW cars.

As for the Transfer case, change the output seals and I bet most the leak goes away..

Most likely, you only need to replace the yoke seals - not a difficult job at all, you don't need a shop to do it.

First you have to take into consideration Dave's position. He probably answers 100 emails and messages daily. Those are not making him money so they are going to be short. I just dealt with him on a problem and although short and sweet he answered the question and solved the issue. You find 1otber person with his knowledge out there. If he fired you as a customer you must have deserved it.

Which disco is this for d1 or d2? If d1 4hp22 you can just put a 4hp24 in with a hgm compushift and run the whole transmission from your phone. Secondly check with Erickson industries. They are zf specialists here in the states. just don't piss them off too. Maybe they can help. Lastly the 4hp22 is a stout transmission and if you just rebuild it, it will hold up fine to what your doing.

Think you should have just let your local trans shop deal with Ashcroft. These guys don't like giving out info they consider proprietary.

I've got an Ashcroft upgraded transmission and transfer case. Both leaked within 1 month of freeway use. If I could go back in time, I never would have spent the cash bringing those over from the UK. Would have been better off doing it locally.

To Dave's credit, he did respond quickly to my emails, but had nothing to offer regarding fixes other than pointing out exactly what the problem was. I ate the cost to fix their issues.

With that said, you should check out Level 10 in New Jersey. They do upgraded 4HP24 / 22 transmissions and know their stuff. No idea on price, but it's where I probably would have gone had I not gone the import route.

Level 10? No thanks. If it doesn't go to eleven, I'm not interested.

We use the 4HP24eh behind the Cummins R2.8. Given the Cummins is 310 ft # without a tune we’ve been using Ashcrofts stage 2 builds when the the customer wants an automatic. Not Midwest but friends with rover shops pointed us to Erickson Industries in Ct to build us one during Covid when Ashcroft couldn’t supply anything. Had Tillery ship them a core & 3 weeks later a fresh trans arrived.
