Torque de transmission pano? - 2003 Pontiac Grand Am

Il semble que vous rencontrez des probl?mes de transmission avec votre Lincoln Town Car 2001. Ce genre de comportement peut ?tre caus? par plusieurs facteurs, tels que :

• Un capteur de position du levier de vitesse d?fectueux ou mal r?gl? qui emp?che la transmission de savoir quelle vitesse est s?lectionn?e.
• Un probl?me avec les commandes ?lectroniques de la transmission, comme un bo?tier de commande de transmission d?fectueux.
• Un probl?me avec le syst?me de contr?le de pression de transmission (TCC) qui emp?che la transmission de passer en mode de conduite.
• Un probl?me avec le m?canisme de commande de la transmission, comme un c?ble ou une liaison de levier de vitesse endommag?.

Il est recommand? de faire diagnostiquer votre voiture par un m?canicien professionnel pour d?terminer la cause exacte du probl?me et pour pouvoir r?parer ad?quatement. Il est important de faire r?parer le v?hicule rapidement pour ?viter des dommages suppl?mentaires ou des probl?mes de s?curit? potentiels.

If you have true 4-wheel drive as opposed to all-wheel drive and you were driving on a dry surface with four wheel drive engaged, you may have "wound up" torque between the front and rear drive trains. This happens because when turning, rear wheels take a shorter route than the front wheels and this difference has to be compensated for either in the transfer case or by slippery or snow covered roads, or it will bind, and the resulting pressure makes moving the selector very hard. You have probably felt this happening ("bucking") to a lesser extent when making tight turns while in 4WD in the past?

If this is the case, all you have to do is jack up the front end - and preferably get both front tires off the ground. The jeep should NOT be running. If it was "bound up," this will release the pressure and you will probably see the front wheels spin a bit. You should then be able to move the selector back to the two-wheel or all-wheel drive position.

Good luck.

they is correct.
the they can fail you for the transmission.

i'd replace the relay first
or test its output. at 50 mph. (not easy)

3speed or 4 speed transmission>?

ill detail the 3L40 ,3sp first
the PCM/ECU commands TCC lock up.
the RELAY on the right front fender closes, sending
12vdc to the transmission, TCC PIN, and inside the TCC
solenoid opens. sending hydraulic fluid to the lock.

make sure the transmissions ground strap is present and not missing or damaged.

the newer car, about 1995, Suzuki removed part 6 above.
the pressure switch, (just short the wires there)
TSB revisions.

tell which transmission for better help

My spanish is not good, but the solenoids are inside the transmission.

Revise los niveles de liquido en transmission, si estan bien o recientemente ha hecho un cambio de fluidos y filtro, podria tratarse de un problema con el "convertidor de torque" o valvulas de solenoide defectuosas, estas ultimas se encuentran internamente dentro de la transmission.

The transmission in this truck is shifted by a computer based on many input valves sent to the Transmission control module which is part of the powertrain control module (PCM), so what must be done is to have the system scanned for fault codes and also live shift data info look at by a trained dealer tech who knows the system and what to look for. The very least you need is a live data scan tool and a factory service manual set.

came off the trans and remove the torque converter remove de seal don care if you broken the old one and put the new one be safe of dont blend or broke when you install put back the torque converter and make shure to engage in the gears inside torque 3or 2 gears one at one and reinstall the tranny back and fill the oil again p.d i recommend drain the oil trans after to remove trans also verify not leaksand change the pan gasket and the trans oil filter too espero haberte ayudado y suerte my friend

P0735 VOLKSWAGEN - Gear 5 Incorrect Ratio
P0735 se detecta cuando A / T no se puede desplazar a la posición 5 ª marcha incluso si el circuito eléctrico es bueno.

Notas técnicas
Empieza por inspeccionar el nivel de líquido de la transmisión y el estado, y el líquido cambia si es necesario.

Este diagnóstico monitores de la posición real del engranaje de control de la relación de deslizamiento del convertidor de par calculado por el Módulo de Control de Transmisión (TCM) de la siguiente manera:
Convertidor de par deslizamiento ratio = A x C / B

R: El eje de salida de la señal revolución de la revolución del sensor
B: Motor de la señal de velocidad del motor del módulo de control (ECM)
C: Relación de cambio fijado en la posición del engranaje que supone la medicina tradicional china

Si la posición real del engranaje es más alto que la posición (5 º) supone por TCM, la proporción de deslizamiento será más de lo normal. En caso de que la relación es superior al valor especificado, los jueces TCM este mal funcionamiento diagnóstico.

Los síntomas:
- A la luz del motor (o motor del servicio pronto luz de advertencia)
- Cambios de la transmisión incorrecta

Posibles causas:
- La transmisión de bajo nivel de líquido
- Dirty líquido de la transmisión
- Turno de solenoides
- Problemas de transmisión mecánica
- Transmisión del circuito de control hidráulico

Espero que esto le ayude. Por si acaso, adjunto el detalle en ingles original.

Suerte.

P0735 is detected when A/T cannot be shifted to the 5th gear position even if electrical circuit is good.

Tech Notes
Start by inspecting the transmission fluid level and condition, and change fluid if necessary.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:
Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (5th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible Causes:
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

either front clutch has gone or the operating piston for the same and without a good look at it i couldnt honestly say so ask a local mechanic to have a look for you is about the best advice i can offer .Could also be the drive plate for the torque converter has broke away as well so ask a local mechanic sorry for not giving a nice quick fixya answer

If your vehicle has the 5.2 liter,aka 318 cubic inch engine,there is only one transmission model applicable and it is the 42 RE which used to be designated the A500.It is a 4speed overdrive transmission.If installing a rebuilt trans and new remanufactured dry torque convertor.You add 4 quarts initially,then fire the engine and add another 5-6 quarts for a total capacity of 9-10 quarts.Fluid level is checked with the trans in Neutral.If you are only dropping the pan,you will replace roughly 4 quarts.The transfer case fills separately,but uses the same automatic transmission fluid.Capacity for the transfer case is about 2 quarts/fill to the bottom of the fill plug hole.Good luck.
