Hi all
We bought a 2006 Sahara in July 17. Picked up Aug from Toyota. Sep, replaced Chipit Chip with a DTE chip. Have driven about 1000k before transmission stuffed itself. Oct had transmission rebuilt. No upshift from 4-5.
Went to Toyota to diagnose. No fault found. Went back to transmission rebuilder...no fault found. Went to Chip installer...no fault found.
Do it ourselves...found a few faults....Turbo boost sensor stuffed. Throttle motor controller - pins corroded (now cleaned). L4 position switch replaced. Still no 5th.
Using ATF WS oil in transmission.
We have borrowed a Snap on diagnostic kit and checked all pinouts. Found a couple more issues but we are yet to find out why upshift to 5th not working. It has intermittently worked a couple of times where it has shifted to 5th and locked in but with no explanation as to why.
Does anyone have any ideas as to what could be wrong?
If we find something in the mean time, I will give you an update.
