91 ACCLAIM TRANS DROPS TO LIMP MODE 3rd gear WHEN TURNING LEFT

[mclick]

My 91 Acclaim drops into 3rd gear when I make a left
turn. I took the car to a transmission shop and he had it
for a month. He replaced the selinoid and several corroded
wires. He has test drove it hooked it up to his meters/diagnostics and says it runs great forward and turning right but as soon as you turn left it shifts down. He had a Chrysler mechanic come in for 4 hours to try to figure out what is wrong and he couldn't even find the problem. He said it has to be a wire that is losing connection when making the left turn, something is disconnecting, hitting the wire and losing contact but he
can not find the wire. I asked about the modular and he said he didn't think that would be it.
I am towing my car back home and
praying that someone out there can tell me they also had this problem and knows how to fix it.
