I have my original tranny still almost 118k(99 TL). I want to do a drain and fill and wanted your opinions on doing this. Over the past few weeks when cold out and cruising in 4th gear when I punch it there is a moderately hard shift, a little abrupt and then it goes. Will doing a drain and fill help smooth this abrupt downshift? It only does it when in 4th going highway speed and then slowing for a car turning off and then while still in 4th(40mph approx.) I step on it 1/2-3/4 throttle and it downshifts hard. When it was warner out it doesn't do this. Also wondered if Honda AFT has different weights for different temps. Please give me your suggestions.

 

it may

 

what about different ATF weights, any suggestions for these cold New England months ahead?

 

There is only one Honda ATF weight. Drain and fill you smooth it out a bit. At least it did on my car.

 

mine shifts stranglely when its cold out ... could this be the tranny or is it just cold weather?

 

I have never thought to ask that or read about Honda ATF because I thought any manufacturer would have different weights of tranny fluid. That is ridiculous that Honda has only 1 weight. There should be at least 2, 3 ideally. Whatever I will just do a 3 quart drain and fill whenever weather permits.

 

No one has different weights. Its tranny fluid, not motor oil.

 

there is different weight tranny fluid, it is not all the same weight, at least that is what I have heard from several people.

 

There are different specifications of transmission fluid - not different weights.

i.e. Dexron III, CHrysler ATF+4, Ford Mercon V, Honda Z-1, Esso LT71141 (for the European ZF trannies)

 

Huh? I must have misunderstood or been told wrong. Oh well like I said I will just do a drain and fill with 3 quarts of Honda Z1. I'll do this when I get the pulleys installed, car should be running in top form then.
