I have a 93 LT1 automatic.It shifts hard into second and shifts into third at close to 3000 rpms. The fluid looks good and is full. Iv'e owned the car for about 5 months and not sure if fluid was maintained but it dosent look or smell burnt. Is there vacuum to the tranny? Hate to take it to the tranny shop and get raped.

 

as you see i have a 93 and it shifts hard to if i dont let off it will red line i just thought yhat was the way it shifted im going to watch this had see what everbody has to say

 

Hey repodude43. this hard shifting just started.Im not sure if there is a cable adjustment like in earlier years. Stay tuned.

 

Can't remember the exact year, but Chevy went to the 4L60 tranny around 93, 94 as an upgrade to the 700R. The 4L60 was essentially a 700R with PCM controlled shifting via shift solenoids. If yours has the 4L60, I would first check for trouble codes, as some codes will cause shifting probs as you described. If it has a 700R, you can try the detent cable adjustment, but since the problem just happened, I would be more concerned with a valve sticking in the valve body. Pull the transmission pan and see if there is any brass fillings or sludge (clutch material) in the pan. Might be a sign of transmission failure down the road. [:-]

 

93 has 4L60 no cable good luck are you getting any code are did your check engine lite come on and no it has no vacum going to it

 

Thanks for the replies, i will check codes.sounds like a rebuild may be coming!

 

If it does need transmission, GM offers a rebuilt one with a 3 year, 50,000 mile parts and labor warranty, also Jasper Engines has a good unit with a 3 year, 75,000 mile parts and labor warranty. We use Jasper products a lot at my shop and they make a good product. [8D]

 

Does the TV cable needed to be adjusted periodically?

 

No, not usually. Only when transmission work is done or replacement is performed.

 

Thanks everyone for the feedback.I ended up having the fluid and filter changed. It was probably the original fluid,it was pretty dirty,but there wasn't any sighns of metal.It shifts a lot better.
