just got the SY3500 converter installed yesterday. great converter, just one thing. it seems after an extended period of driving at high speeds when you slow back down to a stop and start to go again at normal speeds the tranmission shudders on the 1-2 shift and a slight shudder on the following shifts. that is just at normal acceleration. why would this be occurring?

 

I had problems with my Yank 3000 before I installed a B&M Supercooler 24,000GVW. Now it is perfect. Actually it was the Tranny overheating. It goes into "limp mode" at 220 degrees.

 

ah i see, well installed a b&m supercooler at the same time of the converter installation, so i dunno <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

Recheck your fluid level.

 

fluid mark is right in the middle of the cross-hatched "hot" area, so thats fine.... <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> maybe my tranny cooler isn't flowing right??
