4L30EWrong gear start/wrong shift pattern
Unlike the other GM transmissions which use a pair of normally open shift solenoids, the 4L30-E uses one nor-mally open and one normally closed solenoid. It is critical that each solenoid is in its proper place. Althoughthere are tabs on the solenoids to ensure proper location (fig 1.) these tabs can be easily bent allowing them to beinstalled incorrectly. When installed correctly the tabs will face each other (fig 2.) It is almost impossible to tellthe two solenoids apart other than by the alignment tabs, the normally closed 1-2/3-4 has its tab at 10 o'clockand the normally open 2-3 solenoid is at the 4 o'clock position (fig 1.)
Some customers may express a concern about how their vehicle shifts in the Manual Low or Manual 2 Range.Be aware that the PCM will upshift the transmission to 2nd gear in the Manual Low range. This is normal if thePCM detects a vehicle speed in excess of 30-35 mph.
Some vehicles will not be shifted to First gear (even at a stop) when the selector is in the Manual 2 range. ThePCM does this to create additional traction when on ice or slick roads.

E4ODNo 3rd & Rev. After Overhaul
Some vehicles with the E4OD transmission may loose 3rd and reverse after overhaul. This condition may becaused by a stuck direct accumulator, a leak in the direct clutch circuit or a missing feed hole in the direct drumsupport. If the direct drum is replaced, inspect and make sure the clutch feed hole is present.
Accumulators - 1-2The 1-2 accumulator reduces shift shock when shifting from first to second gear. The accumulator piston is nor-mally pressed to the right by line pressure. When there is a shift from first to second gear, the 2-4 band engage-ment pressure pushes the accumulator piston slowly to the left. As a result, the 2-4 band engagement pressurebuilds up slowly, reducing the shift shock when there is a shift from first to second gear
Accumulators - 2-3The 2-3 accumulator reduces shift shock when shifting from second to third gear. The accumulator piston is nor-mally pressed to the left by line pressure. When there is a shift from second to third gear, 3-4 clutch engagementpressure pushes the accumulator piston slowly to the right. As a result, the 3-4 clutch engagement pressurebuilds up slowly, reducing the shift shock when there is a shift from second to third gear.
Accumulators - N-DThe NEUTRAL-DRIVE (N-D) accumulator moderates a rapid increase in hydraulic pressure during forwardclutch engagement. This reduces shift shock when the D range is selected from NEUTRAL. In the NEUTRALposition, line pressure is constantly applied to the right side of the accumulator piston, pushing it to the left.When the D range is selected from NEUTRAL, line pressure which engages the forward clutch is applied to theleft side of the N-D accumulator by the manual valve. As a result, the combination of line pressure and springforce overcome the line pressure on the right, moving the accumulator piston gradually to the right. This move-ment of the piston moderates a rapid increase in line pressure.
Accumulators - N-RThe NEUTRAL-REVERSE (N-R) accumulator reduces shift shock when shifting from NEUTRAL to theREVERSE range (R). The accumulator piston is normally pressed to the left by spring force and line pressure.When there is a shift from NEUTRAL to REVERSE, the accumulator piston is pushed slowly to the right by thereverse clutch pressure. As a result, the reverse clutch pressure builds up slowly, reducing the shift shock whenthere is a shift to REVERSE.
No line rise can be caused by a sticking pressure modifier valve or damaged spring. The Line PressureModulator Valve is responsible for modulating the EPC pressure and distributing it to the appropriate valves.

AllOBDII Codes
When the federal government introduced the OBDII laws, one of the things they created was specific code defi-nitions that all manufactures must follow. OBDII Codes P0001 through P0999 were defined as follows and mustbe used by all manufactures. OBDII codes P1000 through P1999 can be defined by the manufactures any waythey choose.
