Hello Friends,
I need some advice, I am experiancing interesting symptoms and between my indy mechanics recommendation after visual inspection and the stealerships verbal assement and also a indy transmission specialist with LR RR experiance, nobody has a common denominator and each has a classic opinion.
Initial Symptoms, in this order:
1) Between 1500 and 1800-ish RPM, small waiver in needle (spike and drop repeated), constant throttle position
2) During constant throttle input, in automatic mode, low speed cruising results in massive whole body vibration as if an eliptical driveshaft is installed until either throttle is opened more or closed
3) Takeoff from stop results in massive force thrusting into 2nd from first, neck snapping acceleration...lol, unless babied..This has resulted in the tranny going to protect mode (5th gear only) after the huge slam to next gear, shutting off and restarting returns to normal operation. Occurs in no other gear selections
4) Stopped in traffic, in drive on brake on small incline, releasing brake results in vehicle rolling backwards! This only happened once a few days ago, short pumps on throttle engaged gears and forward momentum began, scary. Lots of honking from behind me....
In manual mode, nothing negative occurs at any throttle position including full and throughout all gears. However, if "cold", hard throttle in first may slam prematurely into second, sometimes resutling in tranny protect mode.
Tranny fluid nasty, but full. Nervous to swap until properly diagnosed as the grit maybe the only reason gears are engaging, if its the tranny. I want to assume torque converter because of the heinous vibration that occured sometimes at low speed and the neutral action on an incline, as if the TC wasnt pressurized etc or building pressure to engage tranny.
Tranny indy shop and LR say no way the TC is problem due to "it would just go out, not slowly" and "their bullet proof", the trucks indy mechanic says he'll do whatever I want but swapping the TC is the same job as replacing Tranny and I may recontaminate the new TC if in fact its the tranny.
I would absolutely appreciate your take on the above symptoms and/or advice on similiar experiances. The costs either way are horrifying and in some cases cost prohibitve, i.e., stealership..
THANK YOU for advice and diagnosis help or sharing with results of similiar experiances, very much.
