Clinking sound

[StinkyDog]

Hey all.

I have a 2006 with the 6-speed. When at idle and in gear, the tranny has started making a clinking sound like something is loose. It goes away in neutral and park and under acceleration.

It is time for a re-build?? If so, what are your suggestions?

The truck has 139000 on it and, yes, the motor has roughly a 100hp tune.

Sounds like you are experiencing the type writer tick that many get, but it is an engine noise. Without hearing it though, couldn't tell you for certain.

I wouldn't describe it as a typewriter sound. More of a rattling in the torque converter area. It shows up after driving and coming to a stop with the truck in gear.

If I put it in park, then back to drive, most of the time is goes away. It pulls strong with no slipping( that I can tell). I did have some higher tunes installed earlier, but I have modified those to work better with the tranny.

I will try and record the sound to see if it is what you are talking about.

Might be a cracked flywheel, or loose converter bolts.

My truck was doing something similar. At idle in park or neutral, and rolling into it without downshifting it would sound like a toolbox full of loose sockets (the best way I can describe the sound). Turns out it was the torque converter, a Suncoast 1056.

I have a feeling that is what it is. Your description of the sound is accurate. A T/C is not too bad on price, but if I am going to pull the tranny, I am planning to build it right.

When they start doing this, how long should I expect it to last?

Thanks for the input!
