One last tranny problem

[W1cked]

Allrighty any idea what one of those cost and it reads fine once you accelerate the rpm gauge anyway

Around the 50-60 range. It should read your idle speed to full speed on the tach to shift the trans correctly. The only time the tach should read 0 rpms is when the truck is off.

The sensor costs about $80, part # E5TZ-17B384-A TACH SENSOR ASY ALL YEARS
and while the tach may work at higher revs, it may still be giving the module erratic readings. And make sure that when your guy set the TPS voltage it was with the engine warm and the fast idle solenoid OFF.

Yeah it was all that and its not that the mechanic didn't catch it its that I bought this truck because someone "tinkered" with it and now we are undoing there messups so to speak so just looking where to start first

Your tach is acting up, won't give the PCM a correct signal. An E4OD needs 3 signals to operate correctly, the Tach, VSS and TCP voltage. plus hydraulic internal pressure. Your mechanic either don't know much about an E4OD or don't know how to troubleshoot them. Give him the list of questions I presented. Remove the tach sensor and clean it if it has any metal shavings on it, if a lot of shavings it may be still good, check the connector for corrosion, or replace it.

Well Oldbull that explains it then because the vss is new the tcp is new and has been set correctly and we havent touched the tach sensor so thanks guys been a huge help!!

Correction after 600 rpm it works great only at idling does it register zero

wicked,,use some commas,,or periods. in your sentences,,to break up where your train of thought changes..makes it hard to read,otherwise

sorry, will do.
