Problem with tranny autostick up-shifting with Jeep Wrangler 2013
Jeep Wrangler 2013 4 door 3.6L pentastar engine with 5-Speed Auto W5A580 Transmission. Am contemplating on buying an HP tuner, provided it can solve one very particular problem I am facing. Am currently using a Superchips tuner on the Jeep and canned tunes but this has not solved my problem.
Here in the Dubai we do desert dune-bashing where we need a lot of high rpms and torque. When climbing some very steep dunes, i put the transmission in autostick mode and set it to 1st gear so that i get maximum torque possible. However the problem is, many a times, especially when the rpms are near 6000+ the transmission will automatically shift to 2nd gear even though I have selected 1st gear. Can we fix this issue with an HP tuner, safely, without bricking the tranny and the engine? Has anybody done this before? If it is possible how do i go about tuning this? Apologies if this is a noob/stupid question; i am new to HP tuners so I will need all the guidance i can get.
cheers
Simon
