No upshift auto transmission
#1 No upshift auto transmission
Hi and happy easter,
I have an issue with my series 3 2+2 from 1972. I have just finished the restoration and the first drive test is not encouraging as the gearbox (automatic) does not not upshift.
It works well when i change manually from 1 to 2 or D to 2 or even the downshift from 2 to 1 or if i star on 2 and change to D but on D i have no upshift.
I checked oil level, vaccum horse connection but no success.
I guess the modulation, Governors might ne faulty, sticky.... i hope at least.
Any idea?
Thanks.
Jerome

I presume you changed the gearbox oil and oil filter?
I had the same problem on another car - automatic gearbox - but this was solved by changing oil and filter. Then again, I probably got lucky...

Salut Jerome,
Inside the Automatic gearbox. Check your gearbox type. If will probably be a Borg Warner model 8. If so, then order a new gasket part no 107281 and filter part no 10726 (=numbers from the SNG Barratt website) . Drain the oil, drop the sump and undo the filter retaining clip so you can replace the oil filter. Please make sure you keep the magnet in the sump!
Pending on what you find once the sump is off, a thorough clean might be a good idea?
Have a great evening

This being a V12, I doubt that it is a Model 8. I would think that it is more likely to be a Model 12 BW .

Thanks.
my gearbox is indeed a 12 BW. I was wndering after you first advice if i had another filter that i might have skipped but not. The filter which is at the bottom was cleam when i "check" the trans before to filt it back on the car.
Thanks again for your help.

Not the most technical remidie but might be worth considering.
