Just bought a 2000 Mustang GT, cammed, geared, and stalled.
Let me give you a quick rundown. The previous owner had the VB
built with a Transgo SK. Turns out the trans would no longer shift properly. The shop replaced the VB
with a donor, once again installed the Transgo SK, but also upgraded to Red Alto Clutches, Kevlar Band, HD pump and so on. And a 3500 Edge TC. Using a dyno tune the line pressure was also bumped.
Well the trans doesnt shift THAT good considering. The TC randomly unlocks any speed under 45 MPH, thinking it might have something to do with load because I have 4.10s and it requires very little gas to maintain speed. But im not too sure because at times it allows me to coast with the TC still locked up and ZERO throttle.
Under quick part throttle acceleration the trans shifts to fourth, but then it seems like shifts back to third for a split second, then immediately into fourth, OR considering its a 3500 stall it might be just the converter freaking out before lockup.
Oh yeah the shop used Dexron III instead of Merc 5 saying that it isnt recommended for the high performance parts used in the rebuild!
These are my plans/thoughts. Do a full flush replacing the regular Merc with Merc 5. completely replacing the transgo VB
with a stock unit, with a j mod of course! and installing a trans cooler as well.
Think this would cure my problems?? Any other thoughts/inputs/questions are gratefully welcomed
One more thing, the trans has ~5000-6000 miles on it since the rebuild.
