SOURCE: automatic transmission not shifting into 3rd or 4th

call a dealer and they will tell you you are suppose to change your transmission fluid every 2 years or 30,000miles but if you was carrying this much load you may have over heated the transmission so I would shop around and get a good deal at a transmission place where they can replace the filter and the fluid and adjust the bands on the transmission if needed

SOURCE: cant get 1st gear. 2nd gear nosiey and crunches,

check the gear linkage first for smooth operation, then check/or change your gearbox fluid with the following (before going and ordering a gearbox rebuild - it's much cheaper). Make sure you have it filled to the correct level (see below).

The reverse switch is located on the gearbox, and the switch I have heard, do fail (or you have a short in it's wiring).
Manual transaxle and transfer case:
Hypoid Gear Oil, SAE 75W-90 or 75W-85W conforming to API classification GL-4

Rear differential:
Hypoid Gear Oil API classification GL-5 or higher

Above -23ºC (-10ºF)
SAE 90, 85W-90, 80W-90
From -34ºC (-30ºF) to -23ºC (-10ºF)
SAE 80W, 80W-90
Below -34ºC (-30ºF)
SAE 75W

Lubricant capacities (from the service manuals)
Manual transaxle [to bottom of filler hole]:
FWD: 2.3 L (2.4 qts)
AWD: 2.4 L (2.5 qts)

SOURCE: 88 thunderbird turbo coupe fuel pump

have you checked all fuses under the hood? have you checked the fuel pump relay? you may be able to swap the fuel pump relay with amother relay in the fuse box.are you getting power into and out of the reset switch? from there it goes to the fuel pump. if power is getting to the fuel pump and it has a good ground, the the pump is bad.

Dodge Ram 3500 skips from 1st to 3rd gear, had rebuild after still the same issue. Any advice?


Governor pressure controls the 1st and 2nd shifts. After that is the 3 and 4 solenoids. you would need to look at the pressure when driving(takes a scanner). pressure is 20 to 30 PSI from 1st to 2nd, depends on acceleration. After that the pressure will jump to 100+ psi. Did you replace the governor solenoid and sensor? They are on the passenger side of the transmission and sit in a block that detaches from the valve body.

I got a OBD car fault code po745.,on my Renault methane senic 2003., 106k ml.,what does it means?


P0745 - Pressure Control Solenoid Malfunction Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty line pressure solenoid valve
- Line pressure solenoid valve harness is open or shorted
- Line pressure solenoid valve circuit poor electrical connection Help with this
Tech notes
When the a transmission solenoid is malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.
Help with this
When is the code detected?
The P0745 is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
P0745 Description
The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).

It might be as simple as a plugged filter. Worst case the transmission has gone out and needs rebuilt. Test it by starting off in 2 and see if the car will go to that gear and beyond or not.

HI i Scanned my Ford Explorer to a computer and i got codes P0732 and P0735 can i get a little info about the codes and how to fix the problem


P0735 FORD - Automatic Transmission Incorrect Fifth Gear Ratio Incorrect Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0732 FORD - Automatic Transmission Incorrect Second Gear Ratio Incorrect All - causes would be the same as above with ALSO Probable bad valve body - and or pressure solenoids. Probable bad clutch band. If the fluid is ok and if you have tried changing the fluid and filter to no aval. Is it time to think about a transmission repair at a local transmission shop. Sorry.

1997 Ford Taurus, Won't Shift Past 3rd Gear


Ford is very common for tranny problems. Most likely your tranny will have to be rebuilt. As a mechanic myself, I would suggest taking to tranny specialist to see if i needs to be rebuilt, or if the electrical unit is faulty. It will have to be tested with voltmeter/ohmmeter/multi-tester

Stuck in first gear


automatic transmission will not shift out of first gear. We have replace the solenoids in the valve body 3 of them , could the pcm computer be bad or does the tranny need to be rebuilt? The 2005 ford 250 has only 21000 miles but it did have a snow plow on it. It did pull trailers.
