 Subject: Trans problem, '99 42RE
IP: Logged
Message:
Hello, the truck in question is a '99 3.9, with the 42re. The pump seal was leaking for awhile, so decided to pull it out and swap out the seal. As I was changing the seal, it was of course getting a fluid flush and filter change, and I adjusted the front and rear bands as well. I followed the specifications per the repair manual.
After reassembling I took it for a test drive, and noticed a couple issues. For one, it won't downshift back to first gear under wide open throttle. If you manually put it in 1st it'll go, but it won't kick itself down under throttle. Second issue is early shifting in first gear. It is shifting to 2nd at about 3-3500 RPMS, around 25 MPH, where before hand it was around 33-35 MPH if I remember correcly.
The TV cable is adjusted perfectly according to specifications, and nothing is binding or any noticable obvious problem. The fluid level is also fine.
Any help would be greatly appreciated, thanks.

I had this problem but it was related to a governor pressure sensor, control solenoid and OD switch. The code that came up was 1762. Three parts inside the transmission located after you take off the pan. I was told that you could do this yourself. I however elected to have it done as the parts cost around 400.00 at the dealer and I decided it wasn't worth lying on my back for a few hours. The shop I took it too had a hard time as well as these parts are tricky to replace. It cost 240 for labor including filter and kit so why not. My truck would also not start out in first unless you shifted it into drive directly after starting it. It would then shift into 2 at about 3.5 to 4 rpms. Hitting the gas while cruising it would not down shift to first , instead slowly accerlating. so those parts particually the OD switch in the trans could be the problem. The dealer said that this is a known problem on these tansmissions and recommend that the OD switch changed.
