4r100,What are the best way to get them to firm up the shifts.I find my 1-2 shift lags when towing.Also the t-converter makes a rattling sound sometimes when it locks up.All my trucks have factory tow pkg.

Intalled a Sonnax valve and Tricumulator springs in the valve body, and love the firm shifts now. Recommend this mod to anyone, it's cheap cost me $75 Can. and took me about 1 1\2 hours to install.

Hotshoe, here is a link to the company, from which I order it. Had it dilivered in about 5 days, where I live. The install is easy, just messy. www.techtranstool.com When you do this mod you have to also do a tranny filter and fluid change as well. Also need to borrow a inch/pound torque wrench to torque valve body bolts between 80-100 inch pounds, and tranny pan between 110-120 inch pounds. If you go to this web site there are photos of the install. It's http://community.webshots.com/album/25691972abHADDhZFl
goodluck with the mod.
