I had a poor idle, so I replaced the fuel filter, IAC Valve, cleaned the throttle body, and the MAF screen. This helped a little, but not by much. I wised up and checked the vacuum hoses. Some were cracked, so I replaced them. The idle was much better, but not perfect. I disconnected then reconnected the battery, then drove the vehicle about 20 miles. I noticed that the transmission was acting funny all of a sudden (it hadn't done that before today, when I replaced the hoses) and certain gear shifts were very heavy, they thudded. The worst was shifting from a low gear when accelerating and shifting back when I would brake. When I got home I looked underneath the vehicle and it looks like transmission fluid was leaking. Would changing the vacuum hoses have attributed to this? It's the only change I made today, and before today it hadn't done that at all.
