Transmission inconsistency Question

Sam Capizzi Jr · 07-12-2015, 04:07 PM

3 weeks ago I had a trans line come off the cooler. I fixed line at track and added about 5 quarts of dextron/mec to Type F in my 904. (Dex was my only option at the time). My problem is that the car went 13.65 on the next run which was normal but the following run went 13.45 and stayed fast the rest of the night while there was heat in the tranny. Fast forward to last night. Same deal. Off the trailer 13.62@ 95 Next run 13.41@ 96.5 Made 6 more runs within 2 hundredths Perfect. Then we had a 2 hr delay and the car sat in lanes. Car runs 13.65 at 95 Could the mixing of fluids cause this and if so should I go back to type f or dex.

Thanks in advance
Sam
