Problem!!!! w/ 94 z28 automatic

[94marocam]

I have a 1994 Auto matic 5.7 lt1 camaro z28...
Lately it has been preforming poorly.... Not going very fast and the other day an incident has left me confused.... It was a rainy day... I put the car into reverse and then went back some 2 feet went into [d] and floored it i spinned out for a second and then stopped and my car was stuck going about 10 mph untill i turned my car off and back on. I was told the rear of my car felt a bit rough by somone.. (not professional) and that it may be the differential.... what do I do in this situation.. please help somone.. thank you very much!

so your speedo was saying 10mph while you were sitting still???? or you put it in gear and could go no faster than 10mph???

[sykotic1]

going from reverse to drive after a 2 foot roll and then slamming the gas isnt a good idea imho.

[KaotiKCamaro5]

yeah.. last winter a kid i knew from school did that in his 93 Z28.. just trying to show off.. and he destroyed the tranny. Had to have his car towed home. lol So im with sykotic on this one.. not a grand idea..

Well i put the car into drive and my car was unable to drive faster than 10 mph weven when i floored it... iot was stuck at like 1.5 rpm and only going 10-15 mph.... also when i just floor the gas the car lags a bit and goes pretty slow at first...... a few months ago when i did that.... there was a giant wafting cloud of burn out smoke. now it just starts going very slow... getsw going wuick after a good 4 seconds.. but still the car seems alot slower now.. I just want to know what my problem is .. if anyone hjas any sugestions .. pls let me know what i can do or what would even cause this problem...

[Lotus49]

ummm does it spudder at 10 mph.. or is it a constant hum.. could it be his speed limiter? i think its in the tranny anyway.. maybe u screwed things up.. try unplugging the battery for about 20 min and then drive.. usually any kind of electrical problem goes away when i unplug the battery.. or when i do 140 on the highway...

[94marocam]

I was told this problem could be the diferential fluid ( being as how my rear end leaks) or the 02 censor. need some help!!!

[DaMoNe6969]

i doubt that the 02 sensor, or the rear diff could cause the problems you are having... Sounds like you may have a major transmission or engine problem.. Will it still not exceed 10mph? or did that just happen once?

[89IROC&RS]

yeah neither of those are the cause, i can say that with 100% certainty, take it to a trans shop, id say thats probly where your problem is. you either broke something mechanical or a sensor or something. you probly need trans repairs.

[94marocam]

when i turned the car off and back on the car was able to exceed 10 mph again.... but still the car is pretty slow still..... doesnt burn rubber when u floor it... =(

[CORE402]

need professional assistance, PERIOD!

[ridge_runner]

if its in park or neutral,and you press the gas does it go above 1500 rpm??

[ridge_runner]

oo so it does get going now above 10 mph its just slow??like a slipping clutch??? if thats the case its definantly your tranny

[94marocam]

One thing i frgot to mention in the above posts I made.

I forgot to mention that my Transmission mount keeps breaking... when it breaks, u give the car a little bit of gas quickly and you hear a loud clunk... I have had the mount fixed 3 times now... and the cars preformance is bad even after fixing it... for some reason it goes out every month.... I need help with this situation.. pls help somone!

holly shit, what mods have you done to the vehicle??? sounds like there is something very off with the car, when the trans was done before, did they flush the trans lines and radiator???
