If I drive normal it sifts fine but if I stamp on the gas and put it to the floor from a dead stop it redlines 3rd I have to step fully off the gas and press it down again which sometimes that works but not all the time. Seems to me it shifts when I let off the gas and gas it again when I let the car sit for about an hour then if I run anouther race it does not shift out at all. But the tranny shifts strong when at normal drive. Well I took a look and I noticed that the gear box has a lil leak so I don't kno how long its been leakin so I have to fix that this weekend.could that be the prob? Sorry for the long story guys

 

RU saying it redlines B4 the 3rd shift and you need to release the throttle to shift INTO 3rd or RU referring to it shifting INTO 4th?

 

Shifting out of 3rd going into 4th

 

my car does that too ... wen im on it real hard it wont shift into fourth unless i totally let out of it... does this mean there is somethin wrong with my tranny or r they all like that?

 

the transmission has a "safety" built into it that wont let the trans shift into 4th at wide open throttle. there are kits for the valve body to eliminate it.

 

Apparently GM didn't think it was a good idea to drive 140+ mph

 

lol!!!

 

well this sucks because when i race i bearly win and if i race people that have mustangs they only beat me by like a bumper so can someone tell me where i could get this kit???

 

any transmission shop specializing in transmission work should be able to get one. if you like pm me and i can get ya a price and a kit and get it shipped to ya
