hi all looks like my tc is playing up so going to have to replace it .... mines is a 58 plate 3.6 6speed box can i put in a tc from a 2010 3.6 8speed or will it have to be from a 6speed box thanks

Pretty sure it needs to be from the 6 speed, however there's plenty of refurb units available inexpensively on ebay. Also, I'm pretty sure the 3.6 never had an 8 speed box, so think there's a mis-print anyway. 2015 Range Rover Autobiography 4.4 SDV8

yea i was thinking the same thing just wanted a bit of confirmation before i went back to the person selling the tc and questioned them ....

The 6 speed has a gear level. The 8 speed has no gear lever and an electronic rotary dial. Easy way to confirm. 2015 Range Rover Autobiography 4.4 SDV8

just had a replay back and it has the gear lever same as mine magic

Changed the torque converter last month on my 2008 3.6 (6 speed box) before it gave up all together and killed the box, got a recon one from BMWE39MAN on ebay. After speaking to Doug on the phone (his number is on the listing) there is only one torque converter for the 3.6 and he recommended changing the box input seal which he has on the shelf at the same time, did the valve block bridge seals while we were in there plus oil and filter of course and now no shudder and box changes gear fine.

@ kids2 thats great news i will defo be in contact with him ,i did have in mind to replace the valve seals + bridging adapter but didnt know about the pump seal but change that as well .......is the pump seal the one on the shaft going in the gearbox itself (inside the bell housing ) ?

Yes sir thats the one Doug has them on the shelf cost of £10 end of last year when I did mine. As for the bridge seals think I found a link on here for them (memory not what it was it`s an age thing lol )
