Rev Limiter
Do early C4s automatics have a rev limiter. In other words will car up shift if you hold it in a gear manually to long or will the engine blow?

No Rev limiter on the engine until LT1/5.
Technically, trans should hold a gear indefinitely, if you select that gear manually, but I've seen plenty (of 700R-4's) that shift anyway.
Engine, especially if TPI probably won't "blow"...more likely it will just run out of steam and make a bunch of noise. My Mom had an '86 TPI TA when I was younger...that thing would never shift out of 2ng gear if you held it to the floor (even w/the lever in "OD"). Engine would just sort of peak out and die (accelerate no more), just barely above 5k. Ease off the accelerator a bit, boom, into 3rd gear and off she'd go again! How lame.

At both comments!! That was awesome!Nah...she didn't know. I honestly think that you could have sat there all day long at WOT, 5200 RPM and nothing would have happened. I could be wrong. It wasn't that, that did the car in...it was my younger brother, who sent the car over an embankment, down a steep grassy hill and into a tree that did the TA in.
Happy Mothers day, Mom?
