is it toast?

So I've searched and read up on some of the threads related to tranny issues.. my tranny started the hesitation when shifting from park to drive or park to reverse. Takes a few seconds then clunks. Not always but becoming more regular. Started maybe 300 miles ago. I've ordered a new pressure control regulator and New filters. Plan on replacing them this weekend.

Fluid is full and not burnt.. will check for debris when I drop pan.

Truck specs in siggy. Just turned 100k. Owned since 88k. No idea of previous maintanence. Am I just delaying the inevitable here or what?

Thanks

ok, got the pan off, everything looks brand new..

absolutely NO shavings of any kind in the pan or on the magnet. the magnet is covered with a film of black sludge. but other than that its perfect..


crossing my fingers for the ecp regulator to fix me up..

one question thought as to which one it is.

i read about taking the valve body off to get to it, only removing the 8mm bolts not the 10mm ones..

my question is what is the valve body? lol ive read all about it but havent been able to identify what it actually is..

i see two separate pieces that have 8 and 10mm bolts. one is the black finger looking thing towards the rear of the tranny, , the other is the housing that the other 7 regulators are mounted too..

which one do i remove?

thanks

Just to give you a bit of reassurance. If a trans slips from park to reverse AND it is due to a slipping of discs and internal wear of parts, You will for sure see metal shavings in the oil and especially on the magnet. To give you an example, I've had two catastrophic transmission failures, both started out as slipping from park to reverse. Both times, when dropping the pan, there were some very very noticeable size chunks of metal and shavings in the oil and on the magnet. The oil will also smell very burnt.

Hope that helps give peace of mind and that it is probably something else.

ok, so i found that what i was looking at (valve body) was all one piece.. lol

i removed all the 8mm bolts and the whole thing is now loose, but i cant get it to come all the way out.. seem the main harness is not unplugging??

is there a trick to this? it seems to pull down about a 1/4" then stops.

please help

Got it.. 10mm bolt on outside of tranny in middle of harness plug! Woot woot. On the bench solenoid out waiting for parts.

Anyone give me torque specs and pattern to re tighten valve body?

Also just a note I found a castle looking washer came out with valve body that I've read nothing about. Its the forward clutch orifice. Needs installed back in correct place.
