Question about 1996 Chevrolet Suburban
I have a K2500 5.7L 350 small block. I hear a whistling sound coming from the front passenger side. I usually hear it when I hit about 35 miles per hour and higher, and it stops when I go below 35. Sometimes I don't hear it at all. What are the possible vacuum leaks? I also have transmission problems. The truck drives around fine, except when I'm going up a steep hill. It struggles to down shift, the engine revs, then it goes into gear. Sometimes after its down shifted, it falls out of gear and does it again. I don't know WTF. Some one PLEASE HELP!!!
Please note, I have a 4L80-E Transmission. A 4L80-E does not have a vacuum modulator it has a PCS, an electronci switch controled by the ECM. Also, although it is listed as a K2500, this is a 1 Ton Suburban.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

i have a 95 k2500 350 just put in a new tranny and less than 90days later there is little to no pressure. Thinking it is a bad pump but could be the ecu thing as well since the previous tranny went out the same way. If you know where to locate it any help would be great! c = 2wd k = 4wd

Their are a few possible causes of this. One their is not enough tranny fluid in it or the kick down cable is not hooked up properly. the kick down cable also runs the vacume to the transmission.
Check theese and give me feed back to further assist you.

your transmission has possibly been rebuilt with stronger springs put in. No worries. have been running mine for along while without any problems. Better this than slipping, but it is a bit annoying.

check fluid level, make sure proper fluid is in transmission otherwise take to trans shop to diagnse if level and type is correct(check at idle normal operating temp)
