Hi Im David, thanks for visiting the site. p0735 code is gear 5 incorrect ratio, this indicates that 5th gear inside the transmission is slipping and not performing as it should. A gear ratio code like this indicates internal hydraulic or mechanical failure of the transmission, the o/d bands were very common for breaking in these transmissions as well as the overdrive servo bore in the aluminum case wears out and the piston sticks causing no 5th gear or slipping 5th gear. sounds like you need to take it back apart my friend. and check the piston
the OD drum
Excess transmission fluid will cause foaming in any transmission. Foam does not flow like oil, reducing cooling and lubrication. It also implodes on compression between gears or in the hydraulics of automatic transmissions, causing severe damage (pitting).
In an automatic transmission, you will have higher temperatures and poor shifting, as it depends on solid hydraulic pressure, not spongy foam to move the clutches and bands
thats so hard to guess without a scan tool to interrogate the tcm
use the spring and piston... good find
great news...please accept the answer ans leave a 5 star rating for me if you were satisfied with my assistance. thanks and take care.
