laro4x4 Posted December 16, 2020 Share Posted December 16, 2020 Hello you all,I'm sorry for my bad English, I'm from the Netherlands. I have a Range Rover Classic converted with International 2.8TGV engine, I want to fit a 300tdi automatic gearbox, I have already one with 4HP24 internals, is it necessary to fit a bigger torque convertor? I already ordered a bigger oilcooler from a P38. I can only fit a bigger convertor from MD engineering, they have a complete kit but it costs 895 GBP :-( ..... when it is absolutly necessary I will order the kit.What do you guys think??Cheers, Bart van Dessel 1 Quote Link to comment Share on other sites More sharing options...
landroversforever Posted December 16, 2020 Share Posted December 16, 2020 I think with the HP22 you can only go up to the 'medium' torque convertor. Ashcroft Transmissions will know the answer - @ashtrans Quote Link to comment Share on other sites More sharing options...
Mudmonkey Posted December 17, 2020 Share Posted December 17, 2020 You're correct Ross, from the Ashcroft website https://www.ashcroft-transmissions.co.uk/automatic-gearboxes/zf4hp22.html Quote "Small" is used on the 300 Tdi, P38 diesel and the TD5. "Medium" is used on the 3.9, 4.0 and the later 4.6 P38. "Large" is used on the early 4.6 P38"s. Note the large converter can only be used with the stage 2 as it will only fit the 4HP24 front end.

smallfry Posted December 18, 2020 Share Posted December 18, 2020 Large converter will only fit the GEMS type gearbox oil pump. NOT the later THOR type Quote Link to comment Share on other sites More sharing options...
