Re: '94 Tbird LX V8: 4r70w "Headache" tranny
'owdy,
I got the 'boid from the mature orig. owner in '97 with
18k mi. on it. No evidence of bad treatment of any kind.Around 28k mi. I got the shudder when shifting from 3rd to
4th. Had a dealer drain/change tranny fluid and the shudder went away (and hasn't come back). Cost maybe $120.Around 38k mi. the present malfunction began. At 30-60 mph, it would be just *as if* I'd shifted into neutral. Motor revs up but no power to the wheels. Or sometimes, at hiway speeds, it felt like it had shifted itself down to 3rd or even 2nd gear. Lately it feels like neutral: then I set the - selector- to neutral for a second or 2, then shift to Drive, and it gets back to normal. But it scares po' me ...
Around 48k mi. I had another drain/change using Mercon 5, hoping that would help. It seemed to for a while, but by around 53k mi. it was back to it's old tricks.
It now has 59k mi. on the odometer.
There's a wealth of thoroughly confusing literature on the '94 4r70w? I remember seeing a Tech. Svc. Bulletin that recommended replacement of the trans, the EFI, and the computer. Might as well drive the thang into the river ...
Seriously, I got no $ to speak of, and I'm stuck with the 'boid for the foreseeable future. Surely can't drop it off at the dealer and say "fix it": they'd financially crucify po' me. In a lot of ways (not the tranny) it is a "good car" ...
I have driven the car like it was made of thin glass: to my knowledge it has never had hard usage. All maintenance up-to-date, etc.
Is there any inexpensive way to positively identify the problem with the 4r70w? I'm afraid I've got no money for a "fishing expedition" ...
TIA, Puddin'
