If the mileage is high it may be worth getting a Sonnax main pressure valve fitted. Worth doing a vacuum test first, but I find that I need to replace quite a few.

Unlike the 6-speeds, the solenoids on the 5HP24 are generally very reliable



Based on your symptoms, itís also worth checking that your upper valve block doesnít have a crack in the SV-1/KV-F circuit
