Aleight, the other day i took the camaro for a drive around the block a few times just to keep everything lubed and working. I drove it around twice just in OD and it shifted fine through the gears, no hard acceleration. Stopped and talked to the neighbor a minute and went to leave, left in D then i dropped it into 2 and gave it 3/4 to WOT and let it climb a hill then shifted it into D but it didn't change gears and maxed out the rpm as if it was in neutral or spinning the rear tires. Got off the gas and aftera second it shifted. Alright so then i stop and try running it up in D does the same thing at WOT, but it shifts just fine at regular driving speed manually or in D. The trans is a 700r4 that has been modded with the corvette servos. Could it just need some time to warm up since its not a daily driver or its almost like when i shifted into D the rearend broke traction, if this is the case i will be thrilled to deaf that it can do this.Otherwise the trans shifts nice and firm i just want to know what this is.
