Motorcraft Synthetic Manual Trans results feedback:
Picked up my car yesterday after having the Motorcraft XT-M5-QS Synthetic put in it.
Right out the parking lot I put it in first and drove around slowly with the radio off.
I made some turns from lock to lock, on and off throttle listening for noise.
The gear noise from the diff seemed more quiet and shifting is about the same but slightly smoother and easier.
All I have is a SURE RMM no other bushing upgrades or mods.
First cold drive this morning. Shifting into second was my only minor gripe previously. It would almost always grind just a little bit when cold.
Now it's better, but not a lot different when stone cold. Happened to me right after leaving my driveway and then never again on the way to work.
It improved almost immediately once there was some heat in the motor so I'd say it was worth the $70 ( plus tax ) for the Motorcraft stuff.
Actually what's more remarkable is the smoother idle after the oil change! I was running Castrol GTX synthetic and only had 3700 miles on it. I put Mobil1 Super Synthetic in it this time as it was less expensive by about $4 for the 5qt jug at Walmart. Idling at lights is surprisingly smoother now. I've never noticed that before.
