Trans has been rebuilt by pro with 40 years experience.
Codes and goes to limp mode every time I drive over 90 kms/per/hr.Simple reset restores trans.Smooth operation in all other areas. Scope shows SLU soliniod ingagement and holding threw range. Shows consistantly, a sharp movement in the SLT soliniod just before limp mode kicks in. Accurs only at speed.Seems to be getting a reduced duty cycle signal from the TCM suddenly at this point. SLT is Listed as Normally Open. Looking for help with the next step. Cheers

    My car is a c70 year 2001 autogearbox with aprox 43000miles.

    Thx Magnus Andersson Stockholm Sweden magnus_a_99@hotmail.com
