Automatic Trans.

Jolting shift into reverse when cold

When I first shift into reverse to back the car out of the driveway it really jolts hard into gear. This is a 727 trans on a '66 Satellite. Subsequent shifts into reverse (after the tranny has warmed up a bit) are smooth. Adjustment issue? Fluid too high or low? Or a sign that something is wearing out? Thanks!

Never Never NEVER Ever EVER EVER shift a torqueflite into reverse before you put the trans in a forward gear!!!!!!
It's best to start the car in neutral and then put the trans in drive (or any forward gear) first then shift into reverse. Esp when the tranny is cold.

The low reverse band builds alot of pressure when first started and esp when the trans is cold and when you shift it into reverse first it SLAMS the band when it applies it and it WILL eventually break the low-reverse band.

ALWAYS ALWAYS ALWAYS shift the trans into a forward gear first to relieve the pressure on the low-reverse band and save yourself some headaches and $$$$'s down the road.

Cause one mornin when ya go out to go somewhere and ya start the car and drop the trans into reverse, and you hear a loud bang!!!! Then ya'll know why I said the above!!

Also make sure that the engine isn't on fast idle. This is also very hard on reverse bands.

Ck I don't know much about this newer stuff I doo good to keep up and remember what I once knew!! LOL
But it's become a habit with me over the years and even today in my newer FWD cars I still ALWAYS put the trans in an forward gear before I shift it into reverse.
