That's probably the sum of it, really. And more efficient shifting /lockup, probably.It had a "sport" and "normal" selector but didn't appear to drive much differently to any other auto apart from the shift points.
Mmm, 5HP? OK, that's interesting.
Mind goes off at a tangent regarding possibilities.
Ta for the offer of a 4HP, but I am in Cape Town, so shipping will be a challenge...
When I vet back home from work, I will be visiting a mate who knows the BMWs well to pick his brain about the box and it's electronics.Yeah bit of a bummer that!, guess you need to keep looking, should be plenty out there for you.
So, it turns out it's a JATCO JR502E transmission.
This is all based on observation and anecdotal only as I have not yet got to this point in my plan, but the Discovery box will have a long shaft that is not suited to a rear wheel drive application as it is not threaded to accept a flange nut, and will be too long for an extension housing, too.Whats the last word on the best tail gearbox to use. Does the jag tail end fit without driveshaft shortening?
Is it easier to swap the land rover bell housing to a jag box or the tail section of a jag box to a land rover? (guessing the latter, inhibitor switch not present on jag box)
It's a great thread. Even I succeeded based on this information. However as I had none of the bits and the logistical problem of Living in Switzerland, I got everything from Andy. I have driven a Triumph Stag using the 4HP conversion and it is a revelation within the expectation of what an auto does to the "sports car"/tourer experience - it works better than in the P6 IMHO. It works especially well with cars which have a fairly low final drive (i.e. all British sports cars) as the "over-drive" is so large and the lower 3 gears are pretty much exactly where you had then before.Hi All, just found this thread today. I’m still reading through it TBH, but been helpful so far even if it is just finding a group dealing with the ZF-4HP22 in classic motors, I’m not alone. I am a bit of an imposter though, I’m actually planning to fit the ZF to a Triumph TR5, naturally as they were never built with autos there is zilch to be found on any relevant forums. A motorcycle accident several years ago meant a left leg amputation, hence the modification.
Will be back with some questions I'm sure
