Talking I am back with Videos of the transmission problem.

Dont know jack about automatics but story goes. Transmision was working flawlessly one day, drove home got some sleep... Woke up the next morning and the car WILL not shift into second (Cold or Hot) Just stays in first till about 30mph or around 4500R's and just slams into 3rd and then overdrive..
Although I can manually put it in second and from a dead stop it will hold the gear through the RPM range, when going from Manual first to Manual 2nd it slips.

Edit: Yes the fluid level is fine.

Right click and save as please. each video is about 2 meg each.

Shifter in Drive, normal throttle.

Manual 1st to Manual 2nd

Manual 2nd Wide Open Throttle from a dead stop


Tranny shop wont look at it.. they'd rather charge me $1,895 for a rebuild.


I figured videos would be better than words.

1995 Bird.

Is the MLPS the culprit? before I spend half of what I bought the car for on a transmission?

Has your check engine light come on, or has the OD light flashed on and off?

There must be other tranny shops in Portland that could offer better help.

Sounds like the (MLPS) (manual lever position sensor) , It could be anything its hard to say without actually being there but my car was slipping from 1-2nd in between the 2 and I changed out my VB and no more I think it had something to do with the VB or shift kit but there both gone.

Changing out what could be a perfectly normal valve body sounds far fetched. Isn't it better swap out solenoids? All of them, from another 95, or new from Ford dealer.

BTW: My friend just payed $480 for a used or rebuild AODE, installed, and 1 year warranty. I think 1k+ is too much. JustinH said something about build to spec tranny delivered for $400.

Ok I pulled apart the MLPS I think

Drivers side, held in by two bolts, thin, and is located right above the O2 sensor.

Took it apart. cleaned the junk out of it.. the contacts look worn but I made sure they still made contact. electro greased it up.. closed it . . reinstalled it.


same ol BS.

Does anyone know if I can buy a new one from Ford and what they cost?

and if it does not solve the problem can I return it?

Anyways.. thanks for all your help so far

You can buy them from a Dealer yes.

Depending on the Dealer, you will pay around $65.

Can also get them at some local parts store.

You need to check that MLPS with a digital ohmmeter as you move the shift lever through its range. The values and tolerances are in the shop manual. The MLPS also has to be adjusted so its switch positions are centered on the detents in the tranny.

If MLPS is OK, and you do have 1st, 3rd and 4th, your shift solenoids should be OK, and the problem is either hydraulic or some wierd and rare PCM malfunction.

OOPS - forgot the TPS. Bad TPS can mess up a whole lot of tranny function.

Is there a poor mans way to read the ECU codes?

I come from 8 years of experience on RX7's and all I have to do with those is Ground a wire and read the check engine light pulses.. Is there a similar way to do it on the Ford? and if so is there a code list that I can find online??

I very much appreciate your help guys.. Thanks

I believe the only "poor man's" way to read the codes is thru AutoZone, which scans for free (except in CA).

If you ask around locally, some shops will scan for $20-$30.

The TPS (throttle position sensor) costs around $10-$13, and is very easy to replace.

One thing to consider if it is holding 1st and then slamming is the 1-2 accumulator piston and spring.

There is no limit to what you can acheive if you don't care who gets the credit.
