Grumpy Posted December 2, 2023 Share Posted December 2, 2023 Lots if not all automatic transmissions from around the mid 90s are semi or fully controlled by an ECU of some sort. Who has had experience with getting them to work when doing a conversion. For example, I'm thinking of fitting a VK45DE with its factory auto trans to a different vehicle. How easy is it to get the trans to operate? Chairs Quote Link to comment Share on other sites More sharing options...
Kiwibirdman Posted December 4, 2023 Share Posted December 4, 2023 Keep the original wiring loom and ECU from the donor car and it will be OK. Some of the new aftermarket ECU's will control a transmission, they are generally expensive. 1 Quote Link to comment Share on other sites More sharing options...
HumberSS Posted December 10, 2023 Share Posted December 10, 2023 Some boxes you can also buy standalone ECUs for. Th700, ford AODE, Toyota A340, Merc 722.6 etc. Quote Link to comment Share on other sites More sharing options...

Some of them are internal and they are the shit ones Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted December 14, 2023 Share Posted December 14, 2023 A mate put a VH41 into his cedric pillarless sedan. The trans was a total ball ache, so he ended up biting the bullet and buying a stand alone trans contol compter. It was expensive ii4c. I dunno if hes on this forum or not.
