96 saturn multiple trans codes

[gacyota]

So my step daughter has purchased a 96 Saturn SC2 with AT without me looking at it first. It is throwing me P0731, P0732, P0733, P0734 and a P0113. The 0731-4 says these mean no 1st, 2nd, 3rd and 4th. The P0113 is a low voltage from IAT sensor. What is an IAT sensor (I assume it is a trans sensor of some sort) and will it repair this problem?

[gacyota]

well i guess IAT is air intake temp sensor. Has nothing to do with trans. Previos owner says he put a 'shift kit' on this car. I have a feeling there may have been a faulty installation or maybe the computer needs a relearn?

Nevermind, I was able to get the vehicle back to the previous owner and money returned.

gacyota..Just for future refference...A bad or out of range IAC will set trans codes, and so will most other sensors that are tied to the PCM, such as MAP,MAF,IAC, TPS,ECT,ACT, ABS sensors, and alternator rectifier leaking to ground..Never rule out any DTC or sensor code , they will set trans shift codes, and even cause the trans to malfunction.
