update: still have the same issues mentioned below, also happens in 3rd. I have a 65 mile round trip commute, and it only happens on the commute back home. I am at work 8 hours. Last night while driving home on back roads before reaching the freeway at 40MPH at 2000rpm in 3rd I noticed and felt the rpms drop to 1500 briefly several times. This is only happening when driving at steady speeds. Otherwise tranny shifts smoothly, and goes into and out of every gear normal. I dont know if any of this is tied into my idle problem. I keep getting a CEL for idle control valve because of my eratic idle and high idle in park. I spoke to the tranny shop and let them know, and I had thought they wanted me to bring the car back after the first 500 miles after the rebuild to check it out, and the owner tells me all I was going to do was check if your fluid is full and clean. I wouldnt expect my fluid to be dirty after 500 miles
Any ideas of what my problem may be, and should I wait and fix the idle problem first before suggesting another rebuild. My warranty expires in Sept. and I have only put 800 miles on the car since the rebuild.
NOTE: In drive cruising at 65MPH, tach at 2200, rpms would spike up to 3000 briefly, but in 3rd cruising at 40MPH tach at 2000, rpms would drop down to 1500 briefly. What is going on here
