2016 Mustang GT350-R.....A/C Compressor, Condenser/Dryer, Expansion Valve, Flushed the Evaporator & Lines. This isn't the first Compressor failure & the car only has 19,000 miles. Advised the owner to turn the A/C off when beating on the car.
Neat car, Makes you want to beat-on it....Not mine so I refrained.
1956 Chevy 210 Sedan, Cammed LQ4 6.0L & a 4L60E swapped in.....Reverse & 2nd Gear only, But will start in 1st if the shifter is placed in Manual Low. DTC P1860 (TCC PWM Solenoid Circuit fault) present.
The restoration shop that built the car contacted me, I've built a few Powerglides, TH350's, & TH400's for them over the years, They're just now getting into LSx Swaps. Said they had a couple swap specialist diagnose it, Harness has been checked numerous times, PCM has been flashed twice.
The owner of the car supplied the trans, So he trailered it to the trans shop that built it, They installed a standalone controller & thoroughly checked the trans.....Shifts fine & TCC locks.
The Restoration Shop & the Owner of the car are at their wits end with the finger pointing, The shop wanted me to come to their shop, Not going to happen.....All my equipment is here. Out of curiosity I asked if the car can be placed on a hoist....All the hoists are occupied.
Guess the "Swap Specialist" were trying to diagnose this on the ground/car on jack stands?
Car finally got dropped off yesterday after 3 weeks & 14 phone conversations, Good thing because at this point I didn't want to waste my time talking about it anymore....
Test drove it.....Transmission is shifting!!!!
Checked DTC's.....Has a P1860 & P1810, P1810 is for the Pressure Switch Assembly Rationality. Cleared the DTC's......It now has 2nd & Reverse only with 1st Gear only in Manual Low.
Monitored the pressure switch PID's....They're all Hi no matter the shifter position.
Pulled the trans pan so I could back-ground the Pressure Switch circuits, No change on the Scan Tool PID's.
Commanded the TCC PWM Solenoid on.....No click. Solenoid has power & the power passes through the Solenoid Winding. No ground signal from the PCM. Solenoid clicks if power & Ground are applied using my 4L60E/4L80E test harness.
I would usually start at the PCM, But the PCM is under the passenger seat.
Decided to pop the lock/cover out of the Trans Connector, Had 4 terminals pushed out, 3 for the Pressure Switches & the TCC PWM Solenoid.
Trying to reseat the terminals in the connector was unsuccessful, It's a Chinese connecter, A used OE Delphi connector fixed it!!
