4L80E transmission shifting trouble by Russell R
Post New Message I posted this in another thread but I think it is an older one but here it goes.I have a 1996 allegro star motorhome that I had the transmission rebuilt on and this is the first trip on it but is still doing basically the same thing, it's a 4L80E powered by a 454 Chevy engine, the shifts are very light, you can hardly feel them, but I loose speed going up hill, the manual that came with the motorhome says to shift down going up hill, feels like the transmission is slipping and the engine races up but coach still slowing down. anyone have any insight on what I need to do. I was trying to see what type transmission I could change it out to if possible also would like to know if this has a transmission controller located anywhere under the dash that might be a problem. This motorhome is built on a P-30 Chevrolet van chassis.
