I’m hoping someone can give me some tuning information on the 5R55S Transmission. I have recently done some mods and put the car on the dyno with some interesting results. I’m having some problems with possible converter slip or problems with program settings for the Trans.
After reading many threads on the forums regarding the 5R55S it seems to be a little more complicated being it’s a computer controlled trans. The trans is stock right now with a TCI 3000 Stall Converter and a Level 10 Input shaft, I plan on upgrading to the Super Street Fighter later this year, but I’ve had no problems with this until the TCI converter was installed. I’ve already looked into the 4R70W swap but will pass on that for now.
My tuner says this is a slipping converter and is way too loose, so I’m looking at a possible swap to a Circle D Converter. In the mean time I would like to get as much info about what others have done for tuning and how to tune the trans properly in SCT software that is used at the dyno.
What parameters in the SCT Software must be adjusted? I’ve seen people talk about Converter Lock Points, Pump pressure, Mapping, Values etc. that need to be adjusted after installing a different converter or engine mods. I’m looking for specific information regarding this and using the SCT Software so I have a better understanding and knowledge about this trans when working with my tuner.
I have below the list of mods and the results from the dyno, my car is in blue with a comparison car showing proper lockup in red. I should have better numbers from the dyno hopefully will after this problem is fixed.
