This is regarding transmission replacement but I better give some background first! Thanks in advance for any advice anyone can give.
I bought a 2005 TJ (automatic) in Feb. In August it was serviced but I felt some vibration after the roof was reattached. One month later the rear drive shaft fell off. I hadn't been offroad at all. The drive shaft, transfer case and radiator were replaced for $2,500. The car was serviced.
2 days later I took it for a run in the UAE dessert. I wasn't jumping dunes or anything but I was driving on and off for 4 hours in Dubai autumn heat, so the rest periods could have been longer. I lost reverse gear first and then the drive gear followed suit. The mechanic confirmed overheating had shattered the aluminum housing.
I understand the solution involves opening the transmission box and replacing all clutch gears, seals, gaskets and solenoid oils and housing chemicals. The torque convertor also needs draining to have the oils replaced and welded back together (or replaced altogether as a safer option to avoid losing power).
I would like to learn to fix this myself to avoid enormous bills (which are the norm for any reputable garage in Dubai) but don't feel this is the right job for a fisherprice style "my first mechanic" lesson.
My questions/issues surrounding are:
-Did the transmission box overheat or was the transfer case/drive shaft put back together loosely (maybe a bolt got loose and broke the transmission?)...obviously impossible to prove!
-I have been quoted $1,250 for a new set of gears/seals/gaskets and repairing the torque convertor.
Basic set (not heavy duty/racing).
Is it true that there is no heavy duty options for an automatic? This sounds steep, is this price way off?
