Can a torque convertor clutch solenoid cause an intermittent stall condition on a 99 Seville especially when slowing down from a higher speed?
Please help. Does the tranny have to be pulled to replace the solenoid?

An intermittent stall is usually CKP's (CranKshaft Position sensors) A and/or B. Pull your DTC's to find out which, and replace both if the codes pont to them.

The TCC solenoid is a $60 part buried $2,000 in the transmission. It should not cause a coast-down stall.

Sub, I think it CAN cause a stall if it does not disengage. kind of like trying to stop a standard trans without stepping on the clutch. Either should store a DTC though. Have you pulled them?

The only code I get is a 1599 code- stalled condition. I do not get any CPS codes.
I have experienced when slowing down that the transmission kind of lurches forward.

The CKP sensor will not ALWAYS set a DTC.

Ranger, it turned out to be the torque converter clutch solenoid. Had it replaced for $550.00 in Massachusetts and it hasn't stalled yet. I notice a significant dirfference in performance. Thanks

Glad to hear it's fixed. That's a pretty good price from what I hear.

Good to go, and here's a clarification on my post of "the $50 part....."..

The TCC solenoid is "relatively" easy to get to. It's the ISS (Input Speed Sensor) that is murder to replace.

Too many ISS's, VSS's, TCC's, RIM's, CKP's........
