4T65E Trans question

[la1]

I have noticed that while coasting at about 30 mph, if I quickly tap the accelerator I hear a metallic sounding clunk. I don;t think it is the Axels.

could be tranny mount just as well the axles pop your hood have someone watch the engine put into reverse if motor moves more than an inch or2 bad mount or any loud clunking when shifting into drive....i had same problem
