is there a way to reprogram shift pionts

 

Nope

 

nope, cannot be done with hondata too... Only a standalone ecu would be able to do this

 

Does the TL even have electronically controlled shift points? I know it has electronic pressure switches - does the ecu modify the pressure to determine the shift point based on rpm, load, etc?

I have absolutely ZERO knowledge on autos, other than to know I don't want one. I do recall a transmission shop owner that taught the auto repair class here about 20 years ago and he said honda autos (of that time) used essentially the same technology since the 30s. Not sure how true that is now though...

 

the ecu does actually, it also has something called grade-logic that downshifts when you're going uphill

Interesting enough honda refers to the MT CPU as an ECM (engine control module) and the AT CPU as the PCM (powertrain control module), given the MT one runs the engine and the AT one has to run the engine and the trans

there's some info in the FSM on how the AT controls the shift points, but no way to alter them other than putting it into sport mode and manually shifting your AT

there is the megashift/GPIO

MegaShift/GPIO Transmission Controller

granted that's setup there for the 4L60's and getting one to work with the honda AT would be a science experiment in itself but it has enough I/O to handle all of the solenoids on our transmissions

I really don't think it'd be worth the effort, just buy a MT next time

 

I think it would be exaggerated to say they use the same technology they did in the 30s. That said, there has been quite a big amount of A/T failures in Honda in the last decade or so.
That's the downside of sometimes rolling out your own transmissions instead of out-sourcing them (Getrag/Borg/Aisin/etc) or always using the same supplier, if you're not doing so good... well you have to improve or change.

 

Other than manually shifting, I guess not.

 

After a bit more research, I found that Honda developed their Hondamatic transmission in the late 60s. They said it used sliding gears on a parallel axis instead of planetary gears like others. They said they still use that method to this day, so their technology is at least similar for the past 40 years. I'm sure they have had some advances, but I'm not keen on most automatic transmissions. I think they are made of magic fluid and once that fluid is changed, it's like letting all the magic liquid assembly out and they break.
