Well, I'm starting to think that the reason my transmission bangs into
2nd gear, especially under high RPMs and torque, as well as bangs into Reverse, especially when the engine is Hot, is not because of the tranny itself, but because of worn Motor/Engine Mounts.
My questions are:
1) Do worn Motor Mounts generally effect how a transmission operates?
2) Does Heat causes worn Mounts to get worse? In other words, I notice that the "banging" shifts get worse as the engine gets hotter. If the engine is only at 50 degrees in the morning, it's not very noticable, but as the engine reaches 200 degrees, the "banging/clunking" is getting out-of-hand.
I know that the Mounts in my car are hydraulic and are filled with fluid, so I thought maybe Heat would be an enemy, especially once they go bad.
The car is a 1990 Grand Prix w/3.1 MPFI engine and 4T60 transmission. I had the tranny mount replaced with a brand-new OE one about 2.5 years ago, so I doubt it's bad already. I also have had to replace the so-called "Torque Struts" or "Dog Bones" like 3 times. Once, a Brand-New "Dog Bone" actually broke right in half after only 2 days of use!! Obviously there was far too much strain on them. But, problem is, I can't remember if I just had them replace it with a New one, or had them replace the actual lower Hydraulic engine Mounts??? I don't think I had them replaced...
Is there anyway I can check the mounts myself??
THANKS!:)
