How do you get the sensor bracket loose?

[mytrplseven]

Is there a secret to loosening the speed sensor bracket allen screws? Is it possible to do this without removing the heater control valve? I've tried every angle and tool combination in my box to try to get access and It's starting to look like the heater control valve needs to come out. I hope not.

Any one out there that's overcome this. please chime in. Thanks

I bought a foot of heater hose and relocated my heater control valve back and towards the passenger side- I recommend that mod because it not only moves it out of the way of the sensors, but if it ever fails it wont leak coolant into the inspection hole. With the engine cold I lost very little coolant in the process.

If the sensor bracket is stuck, dont forget to remove the third sensor towards the drivers side- the little diagnostic sensor that is NLA and not needed will keep the bracket from coming out

Well, today I pulled off the upper hose of the HCV and moved it out of the way. I plugged up all the miscellaneous holes so nothing would get on the clutch. Guess what? Some idiot in the past (probably the one who left off the shim) used a TORX head bolt instead of an allen head. No wonder I couldn't get the thing to come off. Tomorrow I'll hook up the connectors and see how it goes. Once the bracket was loosened, the shim on the end of the sensor probe method couldn't be easier.

good idea. when replacing my clutch and fiddling with the top bell housing bolt and sensors, had to disconnect and move the HCV off to the side. thougtht I had gotten all the coolant out. but when reinstalling the sensors and BH bolt and went to reconnect the HCV some coolant burped out and went down the inspection hole. I had stuffed a paper towel in it to prevent bolts/etc from going in, but not anticiapted the coolant. glad I had not reinstalled the TT, had to pull the clutch and get a new clutch disc. had a lot of coolant on it. now I keep some alum HVAC tape over that dang hole.
