99 Blazer LT 4L60E Transmission
any one installed any of these ??? ( Transgo, Superior Transmission, or Sonnax) and if so , what were results, is one better than the other, from what i have read on each companys web site , am leaning towards sonnax sure cure sc-4l60e any thoughts or experences that may be helpful ? my problem is that after changing pwm tcc solenoid & the lockup solenoid, i encountered a new problem, shimmy & shake when coming to a complete stop ( not all the time though). converter was not locking out, dropped pan checked lockup solenoid, found a crimp in wire & bare wire showing, replaced solenoid , new fluid , all seemed great then after about 40+ miles or so felt tranny slipping pulled off road, checked fluid ok, noticed a faint burn smell, let cool for about 15 min drove home about 8 miles , so i'm wondering if a repair kit would correct this problem or do i need a rebuild ??
thanks,

Leave the stock on in there and enjoy it.

i have edited my original post, to state the problem as it was not stated before, my fault , thinking too far ahead. i was happy with the stock tranny , but we now have a problem that needs to be addressed.. thanks for any help or guidance to all who post.
