Hello all.
I have a 1993 bighorn LWB 4JG2. It had a slipping torque converter lockup clutch for a long time. I just had the torque converter reconditioned along with a new lockup solenoid. The lock up now works great except when the trans is cold for the first 5 mins or so of driving, if I go over 63km ish (lockup point) the trans will go into lockup and stay locked. If I floor it it will kick down but then lockup again instantly no matter the speed and if I move to neutral it changes but as soon as it's back in drive it goes into lockup no matter the speed. When this is happening and I come to a stop it will stall. If I stop and go into neutral then park it seems to reset. When the trans is warm it operates as normal and will lock and unlock as it should.
Any Ideas of what could be the cause?
I've checked the trans fluid level and it is normal and clear as it was changed a month ago.
Thanks in advance.
