Went with the 30 spline input shaft and he made the other changes for everything it fit. Modified the valve body for firmer shifts. I have come to notice that when the transmission down shifts when I am just coasting there is a "Clank" noise with the shift. I have check to make sure nothing was rattling and have some to believe its the transmission. It seems to drive just fine the olnly other Issue I have is the TCC Solenoid is no good. I have tested it and the coil is shot. I have since moved about 12 hours from the shop the work was done. It is no big deal to me to change the TCC since I have a new one but the noise is my only concern. Any ideas of what it is would be great.
I would check the mounts , drive shaft , U-joints , if you have not.
When this happens , is the shifter in "OD" or "D" ?
