scoobyvoodoo OK folks, as promised I'm reporting back with the results of my trouble and fix.

Appears it was a bad Shift Solenoid 'B'.

Even though I did not have a MIL on I decided to go ahead and scan the OBDII anyway since I remembered I have had codes in the past that didn't illuminate the MIL. Sure enough, a P0755 code, 'Shift Solenoid B Malfunction'. So I replaced the solenoid, put everything back together and have put around 500 miles on it and have not had any other trouble so far. Ta Daaa. Lol.

amc49 'at 60mph, out of nowhere the engine revs and acts like you put the trans. into neutral.'

assuming you were in OD then 4th gear issue.

'it didn't seem do be in 1st but rather 2nd gear pulling very doggy when taking off.'
'but pretty sure it took off in 2nd, it would act just like it did while cruising down the road at 60 in OD....jump out of gear'

Sounds like 2nd gear issue.

Pursue it further, make SURE it is firmly in second and not some other gear, shift manually if you have to to determine the difference. Be sure you're in OD as well.

If convinced the issue then is in 2 and 4 only then a band issue, slipping. Can be broken servo piston, slipping band from wear (need longer bolt)or cracked, or hydraulic issue affecting band application. Possible solenoid issue too. Sounds more like load issue though from mechanical part slipping to flare up.

01 Focus ATX 2.0 SOHC Tranny Issue

Hey folks, I've been reading a lot of the threads and posts dealing with the automatic transmission issues associated with this car. I haven't read anything yet that matches up exactly with the symptoms mine is having so I wanted to run this by you all and see what you think.

After driving for about 50 miles today, at 60mph, out of nowhere the engine revs and acts like you put the trans. into neutral. Then if you let off the throttle, it immediately 'hooks' back up in gear or slams into gear and will pull again. Then it will repeat over an over. Once it jumps out of gear (or whatever it's doing), if you hold the throttle down it will not re-engage until you let off the throttle. I tried it with the OD off and didn't get the same results, but was nearing my destination and ran out of road, so I can't say for sure if it wouldn't do it in that configuration as well. When I came to a stop I put the shifter in 1st gear, and then accelerated but it didn't seem do be in 1st but rather 2nd gear pulling very doggy when taking off. After accelerating while still in the 1st gear position but pretty sure it took off in 2nd, it would act just like it did while cruising down the road at 60 in OD....jump out of gear and then slam back in gear once the accelerator was lifted and continue to pull until it repeated the issue over and over. I did managed to make it home and checked the trans. fluid. The level was right on the money, a nice red color/clean and did not smell burnt or rancid. The car has about 170,xxx miles on it and I did change the trans. fluid and filter about 15K miles ago. No check engine light, no code, will drive in reverse.

So....anyone got any suggestions? Lol. Thanks in advance.

When I get this resolved, I will repost back with the outcome.

Mazda service manual version of the Focus ATX.............98% of it exactly the same and good layout of how many things work, but brother you better be able to understand.........it WILL get deep

Marde ^^ Good post. Thanks for sharing. Yes, please come back and let others know your final results.

Great info!

Had to replace the "A" solenoid in my focus today. It did seem to fix it for the first 5 miles I drove it, time will tell if this is indeed a permanent fix. It was a great write-up, helped a lot! It was shifting from 1-3 OK then from 3 up it would just hit neutral a few times trying to upshift then the computer would go into limp mode and deactivate 4th and 5th gear. Computer threw the usual Shift solenoid "A" code. Shifts occasionally seemed to be hard before the transmission warmed up and I could hear almost a screeching noise right before it would shift into second the first time you drive it when its cold. As of now it seems to shift smoother (but I have not tried it when its been very cold out yet and it might have still been a little warm from moving the car to get it on the ramps). It also would shift very hard a jerk if you let off the gas and got back onto it without going very, very slowly (such as slowing down for a right turn then giving it gas after the turn). I will try and post back more results as I get more miles on the car. Mileage is at 167,xxx right now and has never had anything done to the transmission to my knowledge.

amc49 There are technically TWO speed sensors, one input and the other output, output works the speedo, the other going bad IIRC does not affect speedo but will still mess up the works. The PCM compares them to each other to calculate whether in proper gear or not and slip as in converter lockup.

The 2-4 servo can break or loosen the pin that works 2-4 band, it is pressed into the servo piston. Pull valvebody to get to it. Band can crack or break, the driver side end cover comes off to get to that. The end cover itself can have severe wear issues in it. All fixed without yanking trans completely.

Everybody wants to change solenoids unintelligently let's say, I only change the one that affects the problem, the PCM will tell you since it monitors them. Most solenoids are changed for no good reason at all. The trick buzzword parts to change there since 'everybody else does it'. The shops push it as well, easy high buck job that then usually leads to further entire trans change, the double payback gimmick there.

Tiger-Heli If it is the speed sensor, that is a $25 dollar part and one bolt to remove and replace (and semi-easy access.)

Mine was doing that, but the speedo needle wouldn't move initially starting from a stop.

It's not a bad idea to start with that and go from there ...

FocusManny Okay thanks because they want to take whole trans out and rebuild it and I can't afford that right now. So what can I suggest to them possibly because these guys seem reasonable.


Do you think replacing all the solenoids and fresh fluid would work or no?[/QUOTE]

FocusManny OTE=amc49;96610]You may have 2-4 issues and maybe band there. The 2nd is slipping and 4 (OD) kicks out when PCM detects slipping. If that it can be fixed for way less than that, trouble is no shop wants simple fix any longer, they can only apparently survive by lying to completely change the trans since their guys are not good enough to fix the smaller issues. Many prefer to simply switch out trans now, not even going inside them at all. Could maybe be a speed sensor too. If PCM cannot read clean sharp shaft speeds it sometimes messes up the shifts.[/QUOTE]
