Transmission Solenoid Replacement Cost in 2026

A single shift solenoid replacement runs $200-450 done. A full solenoid pack runs $500-900. The pricing depends on labor time (some transmissions require valve body removal) and how many solenoids you replace at once. Real numbers below.

Single solenoid replacement: $200 to $450 done

For transmissions where the solenoid is accessible by dropping the pan (4L60E, 4L80E, 48RE governor): part $40-90, gasket $20, fluid $40-80, labor 2-3 hours = $200-450 total. Cheap repair if you catch the problem early.

Solenoid pack / block: $500 to $900 done

For transmissions that require valve body removal to access solenoids (6L80, 6R80, 5R110, 68RFE): solenoid pack $250-500, gasket and seal kit $40-80, fluid $80-120, labor 3-5 hours = $500-900 total.

Common solenoid pricing (parts only)

4L60E 1-2 / 2-3 shift solenoid: $30-60 each.
4L60E TCC: $40-80.
4L60E EPC pressure control: $60-120.
4L80E A/B shift solenoid: $70-130 each.
6L80 1-2-3-4 shift solenoid: $80-150.
6L80 EPC: $100-180.
68RFE pressure solenoid: $250-450.

When to replace one vs the full pack

On 4L60E/4L80E: if one solenoid fails, replace it. The others typically last another 50k+ miles. On 6L80/68RFE/6R80: replace the whole pack — the labor to access them is the bulk of the cost. Once you are in there, doing one is silly.
