Hi.
I am new here but have been reading the threads on the 99 ex transmission troubles. I just purchased mine and knew it had troubles but it was a good deal so I went ahead...
I read the post on the vb rebuild and have done the bonded sep. plate and ford update per tsb. I did not replace the electronic pressure control solenoid because it tested within specs.
I evidently had 2 issues and did not know it.
The vb rebuild took care of the 1st, slipping and shift flare ( i only have a very small flare between 3-4 now)
Now the 2nd issue is that when I put the vehicle in reverse it lags a few seconds before engaging and if I put it in drive it either lags or does not engage. I can put it in 1st manually and once moving put it in drive then it shifts fine from there on out.. no codes, no cel or o/d lights flashing. Fluid was like chocolate milk when i tore it down( i used seafoam trans flush to clean it prior to disassembly). no metal pieces and surpirsingly not much soft material in bottom of pan. Does anyone have any ideas ? a lot of posts about slippage but I can't find much on the engagement part.
I appreciate any help.
 






You should have replaced the pressure solenoid, the ohm test only checks the electrical part of the solenoid, The mechanical part of it is a high wear item. It requires special equipment to check it for proper pressure regulation. When there is a problem it is best to replace it. That being said, it may or may not be the cause of your problem. Do an EPC pressure test and line pressure test.
 






Thanks. I wondered afterwards if I should have replaced it. Not realizing it was 2 different things going on didn't help.
I appreciate the insight and all the information posted on here by everyone who is trying to help us all out.
With the transmission working fine after manually starting in 1st then going to drive, I was hoping it wasn't a band. I will try to get it tested and then I can replace the solenoid next weekend and see ...
Thanx again.
