Tranny problem ?

[jbenson]

i've recently had my tranny rebuilt bout 4k ago. now my tranny feels like it slipping. took it back since it's still covered and they hook it up to they're computor no code and everthing come back that tranny was working right. they're thinking that there's a problem with some input to the computor telling it to shift, not shift, or whatever the p.o.s is doing. they're also thinking that it goes with my tach because it bounces around which it's done from the day i got it. so now i have to take it to a electronic specialist for they to find the problem which is now coming out of my pocket, atleast that's what they suggested.

my ? is has anybody got any insight to this. i guess i've never heard of this or let alone can see it possible. guess it could be possible with all the comp. crap in cars these days, im use to working on old stuff.

this is what it's doning when you shift into a gear d,r it seems fine but once you start moving you give it gas the rmps go up but you slowly make speed. i noticed it all of a sudden to wasn't a on coming problem. it's driveable drove it to the shop and work but if there's a hill coming you better get one hell of a run. thanks for any input.

coulpe otherthings, a guy at work said he had something simular happen in his old chevy some shift sensor or something, said it shifted like there was a stage three shiftkit in it. with him saying that mine did seem like it was shifting pretty hard a few days before it started it's slipping. so tonight i brought it home from the shop and was on gravel put it in 1st and power braked and felt fine spun tires. tried d and nothing no spinning just rpms went up. he said the thing they replced was under the hood white box the thought, i see what he's talking about i think but it doesn't say anything like he was saying.
