TRANSMISSION

1995 Toyota Corolla • 1.8L 4 cylinder FWD Automatic • 290,095 miles

On colder days the overdrive will not engage for several (10-15) miles and it is chewing up my fuel economy. After I drive for a while the overdrive kicks in. The problem seems to appear when the outside air temp is below 45 degrees. The colder it is the longer I have to drive before the overdrive will engage. What is causing this and how hard is it to fix

Start with getting the transmission serviced first it may be an oil related problem, let me know if this helps.

I had the tranny services jun of last year. Had the filters and oil changed. The first thing I checked when this started to occur was the oil color and level; both were ok

Time to get it looked at by a professional, I feel that it will bean internal fault, may be a faulty solenoid.

Can the solenoid be removed and the wires spliced/joined to make a permanent connection? Like you can do with the clutch switch that prevents you from starting a manual transmission vehicle unless the clutch is all the way to the floor

No, not as simple as that, keeping the transmission in overdrive all the time will damage the transmission.

Is the solenoid hard to get to and replace or just time consuming? Also how common are the manual transmissions for this car?

Time consuming and can be tricky as it is in the valve body, not something I would recommend that you do as there is a chance that more damage can be done if extreme care is not taken with transmission work, get a few quotes it may not be that expensive having it done by a professional, as for manuals, plenty out there but a big job to do a conversion.
