Have you changed tires and wheels to a different size? If so, that will cause a code to come up. The gear ratio is set as a value in your computer. If you change tire sizes that will cause this problem. You can have this recalibrated at your Pontiac dealer. Good luck! Phil

P0735 relacion incorrecta gear 5 vw bora 2006 solucion


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

Incorrect Gear Ratio, means the transmission is slipping, the clutches are worn out, in other words, you will need to rebuild the transmission which may cost anywhere from $1000-1800. The Kelly Blue Book is about $2800 in Fair Condition, I would pass on purchasing this vehicle unless the person is willing to fix the problem with the transmission and offer you a Warranty for the repair.

The code you are reading is a bit misleading. The gear ratio is not incorrect, the slipping in 4th gear is what the computer is seeing and reading it that way.
Unless you can find a competent shop to do your rebuild, your only other option is to have the shop you are using stop rebuilding the one you have and get you another complete unit. There could be a problem with your original, such as slight porosity in the case, permitting a pressure drop which they are not seeing. (or they are repeating the same mistake each time they rebuild it!
