Please help!!! Is my transmission going out?? Slipping in 4th
Hello everyone. I have a 2002 Z28 A4. The car had 32,000 miles when I bought it. It now has 34,000 miles. I have a few mods done to the car. When I am driving at or around 2000 rpm in over drive the transmission seems to slip a little (sometimes). The RPMs will float up to around 2300-2400 but when I give it some gas it will rev a little higher, then lock back up. It doesn't do it all the time just sometimes. Also @ 60-65 mph sometimes if I mash the gas it slips a little when it down shifts but locks back up right away. Is this the transmission slipping or just the converter unlocking? The car doesn't throw any codes when this happens. I took the car to cottmans transmissions and we took the car for a drive on the interstate. The cottman guy had his little computer plugged into my ECM port but it didn't slip at all until I mashed the gas to let it down shift. The transmission showed no slipping and less than 1% converter slipping. He said that there is nothing wrong with the transmission but yet it still slips. He did say that with a tune at certain RPMS the computer could be telling the converter to unlock. Is this the case? I did purcase a new PTC 3500 stall converter but don't want to spend the money putting it in if I am just going to have to yank the transmission back out and have it rebuilt. Please help if anyone could tell me what might be happening here. Thanks

So if the transmission would be slipping then it would keep slipping and not lock back up? Will the PTC3500 stall converter help? I bought the converter to improve my ET's at the track. With a SLP lid, K&N filter, Gutted cats, MAgnaflow exhaust, a tune, and Micky thompson ET streets DR's I ran a 13.6 @104mph 2.1 60ft 8.4 @ 86 mph 1/8 mile. My maf meter was descreened so I bought a SLP 85mm to put in its place. I also just bought hooker LT's and y-pipe. What do you think my ET will be now. I know this is off topic but just curious. Thanks
