Re: TH350 slipping in reverse
The old rule of thumb test for a 350, is when cold, put in reverse and if there is a delay. hesitation, compared with 1st, there is band wear, and will need an overhaul in the next 10,000 miles.
It sounds like yours has had this for sometime, and is now in NEED of an overhaul
An overhaul is not hard, even if u have no idea how it works, I did mine a couple yrs ago
I dropped it out, put on a CLEAN bench, then starte pulling everything out, laying bolts everything out in order
Then purchased a full kit, and just replaced as reassembled...
BUT once back in, nothing worked, locked in park...consulted and expert, he said I put the park locking lever in the wrong way...right down thr bottom!!!
So pulled out,dismantled as above, sure enough he was right, reassembled , put in adjusted kickdown cable, fired up...and the change was different...
I had also replaced the modualtor, it was an adjustable, took it to the expert, he drove around the block, up on the hoist..pulled the vac hose off the modulator, turned the screw a couple times, pushed vac hose on...backed it off ...didnt even bother to test drive
I made coffee for the guys for morning tea...asked how much...he laughed, nothing...
I dropped in with a couple 6 packs for the guys a few days later.
