Hey guys.... so I posted a few months ago about transmission problems and the only options were to rebuild or get a new transmission. I got a transmission from jasper put in but the problems didnt end there. With 200 miles on the new transmission it went out too! I was not driving the car hard at all just highway cruising and while going up a hill i lot third and fourth gears. Luckily, the transmission was well under warranty and I had it replaced. The second new transmission is already acting up shifting rough and with only 100 miles I lost third and fourth gears again on the highway. We added transmission fluid and it ran fine but it had just been filled with the new transmission. Does anybody have any ideas what the problem could be? Maybe a small adjustment somewhere? Any help would be greatly appreciated.

 

Same kind of tranny that was in the car to start with? IE 4l60e just from jasper?

 

Yea its the same transmission, but according to jasper it has 15 or so upgrades

 

Your not leaking fluid are you? Could it be something other than the tranny, I dont know everything about them but maybe something is throwing yours in limp mode. Tcc broken and computer is trying to compensate or something like that?

 

No, not leaking fluid at all i check it all the time and its still full. I think it is something else other than the transmission, but no one can seem to figure out wat it would be and all computer diagnostics are showing no problems. I always thought jasper was a good trusted name though.
