Knight Rider Posted April 10, 2022 Share Posted April 10, 2022 (edited) Evening all, Got my hands on a 1850 j type overdrive gearbox (through ignorance didn't realise it was an 1850) and was wondering what I would need to do to change the input shaft over to a 1500? Is it just a straight swap? Edited April 10, 2022 by Knight Rider Quote Link to comment Share on other sites More sharing options...
Clive Posted April 11, 2022 Share Posted April 11, 2022 It would need all the gears/layshaft cluster changing too. The gear on the 1500 input shaft won't mesh with the 1850 laygear as different ratios. But if swapping an input shaft it isn't a lit more work.

Knight Rider Posted April 13, 2022 Author Share Posted April 13, 2022 Thanks for the reply Clive. I thought there must be a reason 1850 boxes haven't been converted to 1500s on mass. Looks like I'm on the hunt for a 1500 box!!! Quote Link to comment Share on other sites More sharing options...
