my bronco2 has 180,000 miles on it with no rebuild. i rebuilt the tranny at 150,000 and it does good but when i put foot to floor while towing its like it loses power and then comes back at around 2500 rpms it is stock with 30" ats. What could the problem be. also how do i get the tranny to not shift as hard.

the loss in power might just be the motor, i have a 5spd and mine seems to do the same but usually only a few mins after ive started it. to make it shift smoother you can try Lucas auto transmission fix.

my 2.9 has 240,000 on her still has no problem at redline for most of the day

B2's arent really designed for towing heck my fullsize wouldnt tow that well either. I'm gonna say its more than likely a engine mileage and older tranny issue both acting out at the same time.

yeah that is what its doing just all the time.

the timing was 10* retarded so i put it 2* advanced now its back to beating hondas.

i might be wrong cuz i dont know if 10* retarded is normal or off, but if 10* is normal you should do some more research. it might be something else and advancing your timing might just be curing your symptoms and not your problem

ive got no clue what year or motor your truck is but i looked it up for a 88 2.9L - its SUPPOSED to be set at 10. :shaking:

Yeah, 10 degrees advanced. Check the timing with the spout disconnected...
