Van seems to rev high and not change from 1st to 2nd smoothly. Used to only be a problem when the engine was cool, now seems to be more frequent. The van sort of revs high then kicks into second gear with a noticeable throw forward.

Check if the condition on this TSB apply to what you have

Condition

Some customers may comment on a 1-2 shift shudder at light to moderate acceleration. Typically, the throttle plate angle parameter is 12-20% at time of condition with vehicle speed of approximately 24-40 km/h (15-25 mph). The customer may describe the condition as slip or delayed shift into second.

Correction

Replace the complete second clutch assembly with service kit, P/N 24240561. Refer to the GM Unit Repair Service Manual for the year and model of the vehicle being serviced for the 2nd Clutch service procedure.

This service kit contains: Second Clutch Housing Fluid Seal Rings (613), a Second Clutch Assembly (617), a Case Cover (Channel Plate) Upper Gasket (430), and a Case Cover (Channel Plate) Lower Gasket (429). In addition to the content of this service kit, four other gaskets not included in this service kit will also be needed to complete the repair, a Control Valve Body Cover (Side Cover) Gasket (54), a Control Valve Body Cover (Side Cover) Inner Gasket (59), a Case Cover Lower Gasket (429), and a Case Cover Upper Gasket (430). These gaskets can be obtained by ordering service kit P/Ns 24206959 and 24206391.
Be sure to use ONLY the Second Clutch Assembly and Second Clutch Housing Fluid Seal Rings provided in this service kit. DISCARD the Second Clutch Assembly and Second Clutch Housing Fluid Seal Rings removed from the transmission being serviced.
Disassemble ONLY the Oil Pump Assembly from the Case Cover (Complete).
DO NOT disassemble the Control Valve Body from the Case Cover. Remove ONLY the Case Cover-to-Case bolts to remove the Case Cover and Valve Body from Transmission Case AS AN ASSEMBLY.
To access all Case Cover-to-Case bolts, it is necessary to remove the Pressure Control Solenoid Valve Assembly (322), and 1-2 & 3-4 Shift Solenoid Valve Assemblies (315A, 315B).

.
IMPORTANT:This service kit does not contain the gaskets and/or seals necessary to service the Case Cover and Control Valve Body, if they are disassembled from each other. Please review the graphic above for Pump Body-to-Case (230), Pump Cover-to-Case (231), Control Valve Body-to-Case (377), Manual Shift Detent Assembly-to-Case (805), and Case Cover-to-Case (433, 434, 435, 436, 374, 379, 380, 384) bolt locations.

NOTE:Failure to use the parts in the service kit as instructed will cause improper function, and possible transmission distress.
