1966 Toronado transmission problems!
Posted: Sat Jun 30, 2018 2:48 pm
Hi Guys,
I purchased a very nice older restoration that had not been used much since work was stopped.
It has 80,840 miles and looks, runs and drives very nice EXCEPT!! The transmission will not upshift automatically. From a stop, it starts forward in DRIVE. It’s like a manual trans being stuck in 4 gear. I am a retired restoration mechanic and very familiar with older cars which have sat around so,
Here’s what I know or have done:
1) Oil level is clean and full when hot in park.
2) Trans will start in low and upshift just fine using manual shifter on column!!
3) Reverse works as it should.
4) I removed non-functional factory kickdown switch assy. from engine and installed Bruce Roe’s electronic switch and 1968 gas pedal assy. Switch pitch and kickdown now work great!
5) I replaced the vacuum modulator and confirmed 15-18 units of vacuum at the transmission.
6) I removed the Governor and confirmed the plastic gear is in good condition.
7) Cruising along at 60-70, the car drives and feels great! I am stumped!!! Help?
I am not familiar enough with this transmission or TH-400’s in general so if anybody has a suggestion or direction for me to try, I’m all ears. Failing that, does anyone know of a transmission shop in central Virginia who has the knowledge to R&R and correctly rebuild a Toronado transmission?
Thanks,
