e4od slamming gears

[kadeninabnitt]

This just started yesterday. the truck will slam into gear hard enough it will throw you back in the seat. it does it in any tune wether I've got the pedal matted or grandpaing it, It still does it. there's no od light flashing no slippage just shifting very hard any ideas on what could be causing this? Or do I just need to start saving for a rebuild?

How many miles on it?

Just one shift (like the 1-2) or all of them?

I too would like to hear an answer on this. My buddies 97 does the same thing, he said it staryed after a local shop rebuilt his e40d... hopefully theres a cheap answer lol

I have no clue on the mileage I swapped a freind my 5 speed setup so I could go back to an auto his truck had almost 400k he had just got it before we swapped I figured it had to have been rebuilt at some point but who knows

And for which shift 1-2 is the worst 3-4 isn't as bad 4-od feels like driving an old gasser with a shift kit down shifting feels completly normal

Check the vss wiring. I have found where the brake cable can wear into the wiring back at the rear differential. It won't always cause speedometer issues but can cause a "glich" in the sine wave.

Exhaust back pressure tube can be clogged not giving the transmission the feedback needed for shift...
I changed out a torque converter and a couple fluid changes before I figured out mine was sooted over...

Ill definitely look in to those 2 thanks for the info guys

Thanks for the update I needed to buy a new tube when mine was off because I stripped it out...

 

[kadeninabnitt]

I lucked out on that was gonna just buy a new sensor but I guess its a dealer part parts stores can't get it

 

[kadeninabnitt]

well it seemed like it had been resolved but i took a long trip tonight and about halfway through it started it again im going to remove the sensor maybe somthing got knocked loose from the tube from cleaning it im also going to check out the vss wiring to see if its jacked we shall see tomorrow

Whenever mine does I unhook batteries turn on lights to drain the power to the computers and it resets it, worth a try, my brothers was acting up in Indianapolis one day, slamming gears and every light, got home and did that, also your vss sensor

Have you verified exhaust back pressure with AE or a scan gauge... It could be a bad sensor

 

[kadeninabnitt]

Ill try the batt deal but as for verifying back pressure I don't have access to an ae or scan gauge
