okie dokie. i have a 96 z28 ... i've only had it for a few months. its got 138k on it. from what i can tell the transmission has been rebuilt and seems to have a shift kit .... (i dont know, i have no records)

recently i've noticed like a little skip when i'm driving on the highway -- mostly at around 55-65 mph at 2k rpm's and traveling at a steady speed. the rpm's will be chillin at 2k and then when the skip comes, they jump up 1 or 2 notches and go right back down to two.

it feels almost like a sputter - like it has bad gas or the fuel injectors are clogged or something ... but its been doing it for a while so im thinking it might be the transmission.

soo should i start looking for a new transmission (my boyfriend wants to put a 5 speed in it ... BOO) or what should i do ??

 

The description your giving sounds more like the converter unlocking and locking, Theres a good possibility its due to engine missfire, I would get with a tuner and check that first, 135000 in a performance car is however alot of miles.

 

OHHH. it did throw a code the other day & it was a misfire in multiple cylinders.

soo i probably need a tune up right?

yeah 135k is a lot... but it runs perfect... but then i dont know if its been rebuilt or anything.

 

Sounds like you have your problem , I would get a tuneup and go from there the missfire code will cause the converter to lock and unlock randomly

 

hmm.... weird!! i cleared the code & it hasnt popped back up yet but i'll def get a tuneup soon. thanks!! =)

 

If the computer deems that the misfire may cause damage to the transmission it can unlock the converter for the rest of the ride in some cars!
