just rebuilt my 1995 f-250 5.8 4x4. finally got everything back together and in the truck, got eer purrin like a kitten. except when it goes to shift into say second or third it wants to shift hard. It has e4od tranny does the computer control engine shift speed? what can I do to adjust this. dont really want to take it for too far of a test ride to see if there are any factors also got check engine light on and there is no reader plug in truck, how and where do I get reading. I hope this isnt another $50 free estimate at AAMCO lol. any ideas will be appreciated

 

Ford Fuel Injection » How To Run a Self-Test Here is a link on how to check for any trouble codes. I think I would start there to diagnose the problem.
You could also buy an Equus 3145 code reader for around $30.00 to make the job easier.
As for AAMCO one of the transmission experts here wouldn`t trust them to read their own name.

 

The thing about aamco is that they are good at doing tranny's that they work on every day... IE chrysler and dodge... I have had co-workers tell me they do great work! (they own dodges) anyone else that has a honda, ford, etc says they do junk work. I actually talked to the manager that runs the aamco across the street from where I work and he says 85%-90% of the work they do is on dodges, chryslers, and jeeps... I personally wouldn't take my FORD transmission to the Dodge dealership for work so why would this be any different... If you think a tranny mechanic is needed I would talk to the local guys behind the auto parts counter (find the knowledgable ones - not the 20 y/o idiot!) and they could probably head you in the right direction of a shop if not give you the name of a guy who does work in his own garage....

 

The computer control EVERYTHING in that transmission and any sensor issue on any part of the powertrain will affect it's operation so you need to pull the codes and see what's up.

 

wasnt seeking service from AAMCO was makin a reference as to the free $50 estimate thanks for the info next time I am looking for a free $50 estimate i will try ford first.
Anyone tell me how toi get the codes offa 95 auto parts store unable to pullem

 

See.. Ford Fuel Injection » How To Run a Self-Test

Or go buy an Equus 3145 code reader.

 

got codes of act sensor getting too much voltage
dpfe or evp circuit getting too low voltage a
tps circuit getting too low of voltage.
How do I locate and test. got a book but locating the sensors and circuits can be a pain if not impossible

 

Ford Fuel Injection » Throttle Position Sensor (TPS) Here is a link to checking the TPS. It would affect the shifting.

 

ok so evp and tps are next to each other and coming off same wire cluster each is getting tool low a reading. Where to check for voltage issues ending here. wire cluster branches off into injector plugs as well.

 

I would think the first thing to do is check the TPS voltages with a meter (backprobe the wires)to see just what is there and if the TPS itself is good.

 

get no reading off wires to tps and no reading to wires of evp either. I agree the tps is most likely my problem but not trying mto leave any info out.

 

maybe not using voltmeter properly? never did need one and now im paying the price. any help greatly appreciated

 

You need to set the voltmeter to 12v or 20v DC. You need to ground the neg lead (black) to engine block or other good ground. Then, if possible probe in to the back of the connector plug with the other lead. If that is not possible then pierce the wire insulation with the meter probe to get a reading.

 

will do tomorrow and report back

 

one other thing. The truck appears to be ideling high in park, I am assuming this is also to effect shifting. Will the tps when working correctly tone down the idle? the set screw is adjusted to minimum level. will proble wires if quits raining
