300M not going into overdrive?
Rather than be ripped off by a transmission shop I decided to hire a mechanic from CL - so now I've been ripped off a couple of times and now desperate for some help.
My car was fine one night, the next night I'm driving along at about 30-35 and expect the car to shift up but it seems it just keeps revving. The speedo would reach about 30 then jump up to 50 and bob around then back down to 30 or whatever speed I was going. There are no grinding noises, The car reverses and goes forward smoothly. It's almost like it's stuck in second.
Keep in mind I do computer stuff and am in no way mechanically minded so I'm at a handicap here.
The first guy tells him that the solenoid pack fails all the time and that's the first thing to swap out. He turns up and can't get something or other off because of a stripped torq screw. He puts it together and I at least give him $50 for giving my fluid a change which it needed anyway. It was low but it didn't make any difference.
The 2nd guy came over, I told him the first guy said the solenoid pack and he said sure and put it in after noting the previous guy didn't know what he was doing because some bearings or something were rattling around rather than being where they should be. Anyway, solenoid pack in - no difference.
Now, a third guy I was talking to was giving me all sorts of information and sounded much better than the last 2. I thought what the hell. He came over and said the reason it wasn't shifting gears was because of the motor mounts. Sounds debious. He then jacked up the car and said it's the CV joints that were out (Actually, I knew I needed those replacing so I let him to it anyway). Still, no joy. I raced him around at 50mph and 5K-5.5Krpm. He said if it was stuck in first, you'd be blowing the engine up at that speed, but if it was stuck in 2nd the take off would be sluggish and it wasn't. He said it seems to be shifting up but just not getting to the overdrive. He tells me the probably is electrical, one of three things and I might as well rip all the electrics out going to the transmission and replacing them.
I suggested a speed sensor to the 2nd and 3rd but the 2nd said there'd be a code and 3rd said very unlikely. The 2nd mechanic said he couldn't see the computer on the transmission although he could see the engine computer. The 3rd said he could read both but no error codes.
The only thing that seems odd is that if I move it to the manual position, the lights on the dash appear to flash in some sort of code but I cannot find a way to interpret these flashes.
So given this information can anyone suggest what the heck I should try next? I'm getting pretty desperate to get my car back and working again.
Forgot to add that checking the short runner valve, the rubber inside has worn away and the mechanic said that is why the car is idling high (1.5k rather than about .5k).
