Ok.....im having trani problems once again. I have a 95 z28 automatic with a 2800 stall. First it was slipping in 3rd and 4th when i was all the way on the gas. I had to let off for it to shift. But know its sliipping in all gears. I have to rev it up like to 3500 just for it to take off. So i jacked up the car and took a lil look underneath and the trani bolts were finger tight, and the top 2 wasnt even on. I had the trani rebuilt like not too long ago. So im guessing he didnt do something right. But im hoping its a little something simpler than getting it rebuilt all over again. Maybe a vacum line or something. I checked the fluid and it was full so i know its not that. And i have a date with a 69 Boss with a 429 this sunday at kennedale, So i cant be late...lol. So if anyone has any info or is selling a 4l60e let me know.

 

It could be a line pressure problem, or maybe the 2-4 shift band servo. Also check the big electrical connector as it controls the line pressure and everything else going on in the transmission. If it is the line pressure the tranny most likely will need to be dismantled as it could be a number of things, from a bad pump to internal leaks. Take a look at the servo, big round cover at right front of tranny, if the cover and spring aren't seated properly it will cause bad shifts 1-2 & 3-4.

 

I think its the sprag in the input housing Also there is a good chance the convertor is loosing up. What kind of convertor are you running? Is there anycheck engine light the trans sets code like the engine.[8D]

 

Its a tci 2600-2800, but i checked that and it was tight *** shiznit. And theres no check engine light either, so im guessin its enternal like z28pete was sayin. It could be the sprag also, someone mentioned that to me a couple of days ago. Is that inside the trani or where is it located?
