someone was telling me i might have a stuck forward sprag. i really need to get the car to someplace i can pull the pan off and have a look inside but i live in a apartment now so it wouldnt be good, but im wondering if ive overlooked something and i might be able to fix the prob without pulling or rebuilding the tranny.
also question what rpm should my motor be turning at 60mph on the freeway?

ive never been able to tell but i remember it being kinda high like close to 3000 rpm. im afraid to drive it now since i cant afford to tow it home and it was a pain getting it backed into my friends lot where im storing it along with my jeep. theres a tag on the rear end right? or do i need the vin? i have no door sticker, thats how i found out i have a hypertech chip, theres hypertech sticker on the door where there should be a door tag. i suspect my door has been replaced anyways.

If your car has to rev to 4K to go in reverse and it's reving to 3K at 60mph, either you have a huge non-lockup converter or your trans is junk.....judging by the fact that you said the fluid smelled kinda burnt I'm going to say your trans is junk. If you feel technically savvy enough rebuild it, or pay someone to. Either way I recommend a converter since you will NOT be able to clean out all the little junk that's in there from the circulated fluid. if you spend the money right you can build a great trans for well under $1200. And it will last you a long time. And on another note, get rid of the hypertech as fast as possible, it's not helping any....

what should it be turning for revs at 60 mph?
i havent had a chance to go look at the car but i whent and saw my old shop teacher and he showed me a disassembled trans so im pretty sure i just need to make one tool and ill be good but i havent decided what im going to do. if i can find work ill just buy a parts car if i find one for a good deal

well when people play with trans stuff, they just jack the heck out of the line pressure which can be good, but on a stock trans isn't really great, since it does it through a solenoid, not with the valve body and pump. As for revs at 60.....my 93 spins 2100 rpm at 70, and like 1800 at 60. now it's "technically" a different trans....4L60 v. 4L60E....the internals are all the same except in the valve body with the electronic controls. Back to the Hypertech, get rid of it....it will do nothing but be a hindrance in the future. It will eventually cause more headaches than its worth...IMO

is yours a chip, or a flash program? IIRC only 93's have the removeable chip.....it goes with the speed density engine controls. I've had nothing but bad luck with Hypertechs screwing up the computer and the car. Just my experience.... I think you're trans is either 1. slipping and on it's last legs, or 2. you have a converter and don't know it, or 3. the hypercrap has tricked it into doing something it shouldn't....this is what I can tell you from my experience....

removed hypertech, drove car to trans shop. they said the low reverse clutch bands are probably burnt up.stil drives fine foward but no reverse, if i dont hit the gas at all it kinda wants to back up but hit the gas and it halts like a brake.
anyways no matter what the trans have to come out and since i dont have the money to do anything i may just sell the car or put a 700r4 in it instead since i can get one for next to nothing.
