Allison Transmission Energy Storage Solenoid Valve

What type of solenoid does an Allison 1000/2000/2400 have?

Solenoid G was replaced by the main modulator solenoid, which is a PWM solenoid (Figures 6 and 7). To quickly identify which version of the Allison 1000/2000/2400 valve body you have: The most common problem with the ‘01-‘09 Allison 1000/2000/2400 valve bodies is the sticking E-shift valve, or as it is called on the ‘06-‘09 6-speeds, shift valve 3.

What is solenoid pressure?

Solenoid pressure, or lack of pressure, positions shift valves which apply or release transmission clutches to produce the range commanded by the ECU inputs. The ECU is connected to the solenoids by a wiring harness with sealed multi-pin twist-lock connectors at the control valve bodies. Figure 1–8.

What are the features of the Allison 1000/2000 series transmission?

This document provides an overview of the Allison 1000/2000 series transmissions. It describes the key features and components including: - Five speeds forward with overdrive fifth gear, plus reverse and neutral controlled electronically through six solenoids. - Planetary gear sets and five clutch packs provide the gear ratios and shifting.

Does Allison Transmission offer a service evaluation?

Allison Transmission could not possibly know, evaluate, or advise the service trade of all conceivable procedures by which service might be performed or of the possible hazardous consequences of each procedure. Consequently, Allison Transmission has not undertaken any such broad evaluation.
