H230 Auto trans and replacement options
Posted: Mon Dec 12, 2011 10:48 am
Hi guys,
Seems I now own a 95000 mile H230 260C/Cedric courtesy of kyteler... just drove it up from Invercargill to Auckland but that's a story for another thread.
During my travels, I've noticed it's pulling a fair whack of revs at cruise, granted I've been doing sorta 70mph a lot of the time but still, it would be nice if I could roll around at a bit of a lazier pace.
Currently has a 3 spd auto, unsure on designation but I suspect it's a 3N71 Jatco if everything I read via google is right. Googling also tells me there was an overdrive version of this produced, which was coded L4N71b and produced from the early 80's onwards. So - logic says to me that this would be the right trans to swap into the 260C to allow a cruisier cruise. Yes?
This leads on to asking what vehicles I would be most likely to find one in, and is the swap a pretty straighforward affair (ie. no electronic controls etc, could I use my existing shifter and remote mount the overdrive switch on an already present dash blanking plate).
Additionally - what's the diff these things run? Another option is perhaps a taller diff ratio.
Thanks, Rich
