Automatic Alpine

[nickraymond]

Hi Everyone
My automatic alpine has just been tuned and though she feels good.. she doesn't feel like she's changing down quite right.
I could kick her down, but that tends to burn fuel and shouldn't be necessary.

On slopes/hills she tends to labour slightly in the top gear.
Does anyone know if there is a way of making this happen slightly sooner?
Linkage adjustment, fluid level etc?

She is my only car and I do 1000 miles a month, whilst I don't want to convert to manual, her very top speed is 70, before the noise/pedal vibration becomes unhealthy, the rev counters on about 3k at this point.. so I'm suspecting that the gearbox isn't too keen on those sort of speeds.

Does anyone know of a automatic gearbox which would be suitable to replace the borg warner 35, ideally one with four gears.
Alternatively could I have the third gear inside the box replaced with a bigger gear?

Thank for any help.
Nick

70 mph at 3000 rpm isn't too bad. If you're looking to get better performance on the occasional hill, without killing your gas mileage, can you manually downshift to a lower gear, instead of mashing the pedal to achieve the same thing? You're still going to get the same miles per gallon when you're in second, but you won't have the penalty of gulping lots of gas to get to second gear. I've not driven an automatic Alpine, but that's what I'd do when I'm driving my other cars, and attempting to preserve gas mileage.

You could also investigate changing the rear-end ratio, but that will be a balancing act between performance and economy. You're probably after overdrive... which will surely mean a much more modern transmission.

Good luck!

Automatic Alpine.

If you go to "anugraha.org.uk.rover" you can download the whole manual. You may find the information that you need.

Hi Nick,

A local club member installed a Toyota automatic transmission into his Alpine which I believe worked very well (not to mention the stroker engine and twin DCOE Webers). I'm not sure what car the gearbox came from, but hopefully Alpine_64 may chime in with some more information.

Regards, Robin.

There is an adjustment (see attached pic). The inner cable should have a stop crimped to it (or so the manual says ...) and the outer cable should be adjusted so that the end of the outer cable just touches this stop with the carb at idle. The other adjustment procedure they give involves measuring pressures in the gearbox.

Hi
Thanks for your help
the crimp has come off of the cable and it seems it can only be crimped once, so I think I would take it to a specialist near me to have it crimped and set correctly.

Do you have any more details on which Toyota box it was, or does anyone else have any ideas?

Is it a big conversion?

Thanks
Nick
